Write the prime factorization of the two terms of this fraction then reduce the fraction 3,000 / 6,300
Prime factorization of 3,000:
3,000 = 2 × 2 × 3 × 5 × 5 × 5 = 2^2 × 3 × 5^3
Prime factorization of 6,300:
6,300 = 2 × 3 × 5^2 × 21 = 2 × 3^2 × 5^2 × 7
To reduce the fraction 3,000 / 6,300, we need to cancel any common factors in the numerator and denominator. We can see that both have 2 and 3 as factors, so we can cancel them out:
3,000 / 6,300 = (2^2 × 3 × 5^3) / (2 × 3^2 × 5^2 × 7)
= (2 × 5^3) / (3 × 5^2 × 7)
= (2 × 5) / (3 × 7)
= 10 / 21
Therefore, 3,000 / 6,300 can be reduced to 10 / 21.
3,000 = 2 × 2 × 3 × 5 × 5 × 5 = 2^2 × 3 × 5^3
Prime factorization of 6,300:
6,300 = 2 × 3 × 5^2 × 21 = 2 × 3^2 × 5^2 × 7
To reduce the fraction 3,000 / 6,300, we need to cancel any common factors in the numerator and denominator. We can see that both have 2 and 3 as factors, so we can cancel them out:
3,000 / 6,300 = (2^2 × 3 × 5^3) / (2 × 3^2 × 5^2 × 7)
= (2 × 5^3) / (3 × 5^2 × 7)
= (2 × 5) / (3 × 7)
= 10 / 21
Therefore, 3,000 / 6,300 can be reduced to 10 / 21.
120 plus 120 plus 45 plus 45
120 + 120 + 45 + 45 = 330
20% of the 4,000 Acres were left fallow. How many acres were not left fallow?
If 20% of the 4,000 acres were left fallow, then 100% - 20% = 80% of the acres were not left fallow.
To find the number of acres that were not left fallow, we need to calculate 80% of 4,000:
80/100 * 4,000 = 3,200
Therefore, 3,200 acres were not left fallow.
To find the number of acres that were not left fallow, we need to calculate 80% of 4,000:
80/100 * 4,000 = 3,200
Therefore, 3,200 acres were not left fallow.
Esmeralda correctly answered 21 of the 25 questions. what percent of the questions did she answer correctly?
Esmeralda correctly answered 21 of the 25 questions. what percent of the questions did she answer correctly?
To find the percentage, we can use the formula:
percentage = (part/whole) x 100%
In this case, the "part" is the number of questions Esmeralda answered correctly, which is 21. The "whole" is the total number of questions, which is 25.
So,
percentage = (21/25) x 100%
percentage = 0.84 x 100%
percentage = 84%
Therefore, Esmeralda answered 84% of the questions correctly.
percentage = (part/whole) x 100%
In this case, the "part" is the number of questions Esmeralda answered correctly, which is 21. The "whole" is the total number of questions, which is 25.
So,
percentage = (21/25) x 100%
percentage = 0.84 x 100%
percentage = 84%
Therefore, Esmeralda answered 84% of the questions correctly.
16 2/3/100
To convert the mixed number 16 2/3 to a decimal, we first need to convert the mixed number to an improper fraction:
16 2/3 = (16 x 3 + 2)/3 = 50/3
Then we can divide 50 by 3 to get the decimal:
50/3 = 16.666...
Rounding off to two decimal places, we get:
16 2/3 = 16.67
16 2/3 = (16 x 3 + 2)/3 = 50/3
Then we can divide 50 by 3 to get the decimal:
50/3 = 16.666...
Rounding off to two decimal places, we get:
16 2/3 = 16.67
50% of what number is 0.4
We can start by using the formula:
part = percent/100 x whole
In this case, we know the percent (50%) and the part (0.4), but we need to find the whole, which is the number we're looking for.
So, we can write:
0.4 = 50/100 x whole
Simplifying:
0.4 = 0.5 x whole
Dividing both sides by 0.5:
0.4/0.5 = whole
0.8 = whole
Therefore, 50% of 0.8 is 0.4.
part = percent/100 x whole
In this case, we know the percent (50%) and the part (0.4), but we need to find the whole, which is the number we're looking for.
So, we can write:
0.4 = 50/100 x whole
Simplifying:
0.4 = 0.5 x whole
Dividing both sides by 0.5:
0.4/0.5 = whole
0.8 = whole
Therefore, 50% of 0.8 is 0.4.
The store owner makes a profit of 40% of the selling price of an item. If an item sells for $12, how much profit does the store owner make?
If an item sells for $12 and the store owner makes a profit of 40% of the selling price, we can calculate the profit by first finding the profit as a percentage of the selling price and then multiplying by the selling price.
Profit as a percentage of the selling price = 40% = 40/100 = 0.4
Profit = 0.4 x $12 = $4.80
Therefore, the store owner makes a profit of $4.80.
Profit as a percentage of the selling price = 40% = 40/100 = 0.4
Profit = 0.4 x $12 = $4.80
Therefore, the store owner makes a profit of $4.80.
