Let's represent the unknown number as "x". We are told that the ratio of this unknown number to 64 is the same as the ratio of 5 to 8. Mathematically, this can be written as:
x/64 = 5/8
To solve for x, we can cross-multiply:
8x = 64 * 5
8x = 320
Now, we can divide both sides by 8 to isolate x:
x = 320/8
x = 40
Therefore, the number that is in the same ratio to 64 as 5 is to 8 is 40.

In a class there are 15 girls and 35 boys what is the ratio girls to boys
The ratio of girls to boys in the class can be calculated by dividing the number of girls by the number of boys:
Ratio = Number of girls / Number of boys
Ratio = 15 / 35
Simplifying this ratio, we can divide both the numerator and denominator by 5:
Ratio = 3 / 7
Therefore, the ratio of girls to boys in the class is 3:7.
Ratio = Number of girls / Number of boys
Ratio = 15 / 35
Simplifying this ratio, we can divide both the numerator and denominator by 5:
Ratio = 3 / 7
Therefore, the ratio of girls to boys in the class is 3:7.
Express 5 and half:2 half as a ratio of whole numbers
To express 5 and a half (5.5) to 2 and a half (2.5) as a ratio of whole numbers, we need to convert the decimals to fractions.
5.5 can be expressed as 11/2 (two halves in one whole, and adding 5 wholes to it)
2.5 can be expressed as 5/2 (two halves in one whole, and adding 2 wholes to it)
Now we can write the ratio in terms of whole numbers:
Ratio = 11/2 : 5/2
To make the ratio as a ratio of whole numbers, we need to multiply each part by 2 to get rid of the denominators:
Ratio = (11/2) * 2 : (5/2) * 2
Simplifying, we get:
Ratio = 11 : 5
Therefore, the ratio of 5 and a half to 2 and a half, expressed as a ratio of whole numbers, is 11:5.
5.5 can be expressed as 11/2 (two halves in one whole, and adding 5 wholes to it)
2.5 can be expressed as 5/2 (two halves in one whole, and adding 2 wholes to it)
Now we can write the ratio in terms of whole numbers:
Ratio = 11/2 : 5/2
To make the ratio as a ratio of whole numbers, we need to multiply each part by 2 to get rid of the denominators:
Ratio = (11/2) * 2 : (5/2) * 2
Simplifying, we get:
Ratio = 11 : 5
Therefore, the ratio of 5 and a half to 2 and a half, expressed as a ratio of whole numbers, is 11:5.
48 naira was shared between obi and emeka in the ratio of 3:5 how much did obi received
To find out how much Obi received, we'll use the given ratio of 3:5 and the total amount of 48 naira.
We can think of the ratio as 3 parts to 5 parts. The total number of parts is 3 + 5 = 8.
To calculate how much each part is worth in terms of naira, we divide 48 by 8:
48 ÷ 8 = 6
Therefore, each part is worth 6 naira.
Since Obi's share is in a ratio of 3 parts, we multiply the value of one part by 3:
6 x 3 = 18
Obi received 18 naira.
We can think of the ratio as 3 parts to 5 parts. The total number of parts is 3 + 5 = 8.
To calculate how much each part is worth in terms of naira, we divide 48 by 8:
48 ÷ 8 = 6
Therefore, each part is worth 6 naira.
Since Obi's share is in a ratio of 3 parts, we multiply the value of one part by 3:
6 x 3 = 18
Obi received 18 naira.
Divide 45 Kobo between taiwo and kehinde in the ratio of 4:5
To divide 45 Kobo between Taiwo and Kehinde in the ratio of 4:5, we first need to find the total number of parts in the ratio.
The total number of parts in the ratio of 4:5 is 4 + 5 = 9.
Next, we divide the total amount of 45 Kobo by the total number of parts (9) to find the value of each part:
45 Kobo ÷ 9 = 5 Kobo
Therefore, each part is worth 5 Kobo.
To find out how much Taiwo and Kehinde will receive, we multiply the value of each part by the corresponding ratio:
Taiwo: 4 parts x 5 Kobo = 20 Kobo
Kehinde: 5 parts x 5 Kobo = 25 Kobo
Taiwo will receive 20 Kobo and Kehinde will receive 25 Kobo.
The total number of parts in the ratio of 4:5 is 4 + 5 = 9.
Next, we divide the total amount of 45 Kobo by the total number of parts (9) to find the value of each part:
45 Kobo ÷ 9 = 5 Kobo
Therefore, each part is worth 5 Kobo.
To find out how much Taiwo and Kehinde will receive, we multiply the value of each part by the corresponding ratio:
Taiwo: 4 parts x 5 Kobo = 20 Kobo
Kehinde: 5 parts x 5 Kobo = 25 Kobo
Taiwo will receive 20 Kobo and Kehinde will receive 25 Kobo.
Divide 960 naira between Sola and ayo so that for every 3 naira Sola gets ayo receives 5 naira what is Sola share
Let's represent Sola's share as "x" in naira. According to the ratio given, for every 3 naira Sola receives, Ayo receives 5 naira. Mathematically, this can be expressed as:
Sola/Ayo = 3/5
To find the value of Sola's share, we can set up the following equation:
x/Ayo's share = 3/5
Cross multiplying, we get:
5x = 3 * Ayo's share
Since we don't know Ayo's share yet, we'll represent it as a variable "y". The equation becomes:
5x = 3 * y
Now, we are told that the total amount to be divided is 960 naira. So, the equation becomes:
x + y = 960
We can solve these two equations simultaneously to find the values of x (Sola's share) and y (Ayo's share).
From the first equation, we can solve for y in terms of x:
y = (5x) / 3
Substituting this value of y in the second equation, we get:
x + (5x) / 3 = 960
Multiplying through by 3 to eliminate the fraction, we have:
3x + 5x = 2880
Combining like terms, we get:
8x = 2880
Dividing both sides by 8, we find:
x = 360
Therefore, Sola's share is 360 naira.
Sola/Ayo = 3/5
To find the value of Sola's share, we can set up the following equation:
x/Ayo's share = 3/5
Cross multiplying, we get:
5x = 3 * Ayo's share
Since we don't know Ayo's share yet, we'll represent it as a variable "y". The equation becomes:
5x = 3 * y
Now, we are told that the total amount to be divided is 960 naira. So, the equation becomes:
x + y = 960
We can solve these two equations simultaneously to find the values of x (Sola's share) and y (Ayo's share).
From the first equation, we can solve for y in terms of x:
y = (5x) / 3
Substituting this value of y in the second equation, we get:
x + (5x) / 3 = 960
Multiplying through by 3 to eliminate the fraction, we have:
3x + 5x = 2880
Combining like terms, we get:
8x = 2880
Dividing both sides by 8, we find:
x = 360
Therefore, Sola's share is 360 naira.
Ade and ola share a sum of 4000 naira in the ratio of 3:5 find the amount Ade received
To find the amount Ade received, we'll use the given ratio of 3:5 and the total sum of 4000 naira.
We can think of the ratio as 3 parts to 5 parts. The total number of parts is 3 + 5 = 8.
To calculate how much each part is worth in terms of naira, we divide 4000 by 8:
4000 ÷ 8 = 500
Therefore, each part is worth 500 naira.
Since Ade's share is in a ratio of 3 parts, we multiply the value of one part by 3:
500 x 3 = 1500
Ade received 1500 naira.
We can think of the ratio as 3 parts to 5 parts. The total number of parts is 3 + 5 = 8.
To calculate how much each part is worth in terms of naira, we divide 4000 by 8:
4000 ÷ 8 = 500
Therefore, each part is worth 500 naira.
Since Ade's share is in a ratio of 3 parts, we multiply the value of one part by 3:
500 x 3 = 1500
Ade received 1500 naira.
The proportion of girls to boys in a class is 1:4 if there are 45 pupils in the class how many girls are there
The total proportion of girls to boys is given as 1:4. This means that for every 1 part representing girls, there are 4 parts representing boys.
Let's say the number of parts in this proportion is "x". So, we have:
Girls: 1 part
Boys: 4 parts
The total number of parts in the proportion is 1 + 4 = 5.
Now, with 45 pupils in the class, we can calculate the number of girls by finding the fraction of the total number of pupils that represents girls:
Number of girls = (1 part / 5 parts) * 45 pupils
Number of girls = (1/5) * 45
Number of girls = 9
So, there are 9 girls in the class.
Let's say the number of parts in this proportion is "x". So, we have:
Girls: 1 part
Boys: 4 parts
The total number of parts in the proportion is 1 + 4 = 5.
Now, with 45 pupils in the class, we can calculate the number of girls by finding the fraction of the total number of pupils that represents girls:
Number of girls = (1 part / 5 parts) * 45 pupils
Number of girls = (1/5) * 45
Number of girls = 9
So, there are 9 girls in the class.
