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?

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.

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?

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.

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

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

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

of a cake equally?

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.
