Answer 2

Yesterday, Sarah spent 35 1/2
minutes studying for a test. Emma spent 1 1/2
times that amount studying for a different test. How many minutes did Emma spend studying?

Answer 3

To find out how many minutes Emma spent studying, we need to multiply the amount of time Sarah spent studying by 1 1/2.

First, let's convert 35 1/2 minutes to an improper fraction:
35 1/2 = (2 * 35) + 1 = 70 + 1 = 71/2

Now, let's multiply 71/2 by 1 1/2:
(71/2) * (3/2) = (71 * 3) / (2 * 2) = 213/4

So, Emma spent 213/4 minutes, which is equivalent to 53 1/4 minutes studying.

Answer 4

A middle school band as 2/9 as many band members as the high school band. The high school band has 502 members. About how many members are in the middle school band?

Answer 5

To find out the approximate number of members in the middle school band, we can multiply the number of members in the high school band by 2/9.

First, let's calculate 2/9 of 502:
(2/9) * 502 = 0.222 * 502 = 111.444

Since we're looking for an approximate value, we can round 111.444 to the nearest whole number.

Rounded to the nearest whole number, the middle school band has approximately 111 members.

Answer 6

the answer choices are 645, 112, 45, and 390. Should I choose 112?

Answer 7

Yes, you should choose 112 as the approximate number of members in the middle school band.

Answer 8

How much cake will each member of the team get if 6 members share 3/4
of a cake equally?

Answer 9

To find out how much cake each member of the team will get, we need to divide the amount of cake by the number of members.

First, let's calculate 3/4 of a cake:
1 cake * (3/4) = 3/4 of a cake

Now, let's divide 3/4 of a cake by 6 members:
(3/4) / 6 = (3/4) * (1/6) = 3/24 = 1/8

So, each member of the team will get 1/8 of a cake.

Answer 10

Celeste completed 5/6 of her science problems. Her mom checked 2/3
of the assignment. What fraction of the assignment did her mom check?

Answer 11

To find out the fraction of the assignment that Celeste's mom checked, we multiply the fraction of problems Celeste completed by the fraction her mom checked.

First, let's multiply 5/6 by 2/3:
(5/6) * (2/3) = (5 * 2) / (6 * 3) = 10/18

To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 2:
10/18 = (10/2) / (18/2) = 5/9

Therefore, Celeste's mom checked 5/9 of the assignment.

Answer 12

. Paige decided to paint 4/5
of the rooms in her home last year. By the end of the year, Paige completed 2/3
of the rooms. How much of Paige’s home was painted last year?

Answer 13

To find out how much of Paige's home was painted last year, we need to multiply the fraction of rooms she planned to paint by the fraction of rooms she actually completed.

Given that she planned to paint 4/5 of the rooms and completed 2/3 of them, we can multiply these fractions:
(4/5) * (2/3) = (4 * 2) / (5 * 3) = 8/15

So, Paige painted 8/15 of her home last year.

Answer 14

3/8 divided by 2

Answer 15

To divide 3/8 by 2, we can multiply the numerator by the reciprocal of 2, which is 1/2.

(3/8) / 2 = (3/8) * (1/2) = (3 * 1) / (8 * 2) = 3/16

So, 3/8 divided by 2 is equal to 3/16.

Answer 16

2 1/3÷2/5

Answer 17

To divide 2 1/3 by 2/5, we need to convert the mixed number into an improper fraction.

First, let's convert 2 1/3 into an improper fraction:

2 1/3 = (2 * 3 + 1) / 3 = 7/3

Now, we can divide 7/3 by 2/5:

(7/3) / (2/5) = (7/3) * (5/2) = (7 * 5) / (3 * 2) = 35/6

So, 2 1/3 ÷ 2/5 is equal to 35/6.

Answer 18

simplify that ml

Answer 19

To simplify the fraction 35/6, we can divide the numerator and denominator by their greatest common divisor, which is 1 in this case.

Dividing 35 by 1 is still equal to 35, and dividing 6 by 1 is still equal to 6. Therefore, the simplified fraction 35/6 cannot be further simplified.

So, the simplified form of 35/6 is 35/6.

Answer 20

turn that to mixed number

Answer 21

To turn the fraction 35/6 into a mixed number, we need to divide the numerator (35) by the denominator (6) and express the result as a whole number and a proper fraction.

Dividing 35 by 6, we get 5 with a remainder of 5. Therefore, 35/6 is equal to 5 and 5/6.

So, the mixed number equivalent to 35/6 is 5 5/6.

Answer 22

divide 84 by -7

Answer 23

When dividing 84 by -7, we divide the absolute values of the numbers and then assign the quotient a negative sign since we are dividing by a negative number.

84 / 7 = 12

Since we are dividing by -7, the quotient is negative.

Therefore, 84 divided by -7 is equal to -12.
