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, we need to convert 35 1/2 minutes to an improper fraction. There are 2 halves in 1 whole, so we can rewrite the 1/2 as 2/2. The sum is 35 2/2 minutes.

To multiply by 1 1/2, we add 1 (which is 2/2) to the fraction and then multiply by the whole number.

35 2/2 * (1 2/2) = (70/2) * (3/2) = (70*3) / (2*2) = 210/4 = 52 1/2

Emma spent 52 1/2 minutes studying for her test.

Apologies for the mistake.

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, we need to convert 35 1/2 minutes to an improper fraction. There are 2 halves in 1 whole, so we can rewrite the 1/2 as 2/2. The sum is 35 2/2 minutes, which is the same as 35 + 2/2 = 35 + 1 = 36.

To find 1 1/2 times that amount, we can multiply 36 by 1 1/2.

1 1/2 can be written as a mixed number: 1 + 1/2 = 3/2.

36 * (3/2) = (36 * 3) / 2 = 108 / 2 = 54.

Therefore, Emma spent 54 minutes studying.

To find out how many minutes Emma spent studying, we need to calculate 1 1/2 times the amount Sarah studied.

First, let's convert 35 1/2 minutes to an improper fraction.

35 1/2 minutes = (2 * 35 + 1) /2 = 71/2 minutes

Now, multiply 71/2 by 1 1/2.

(71/2) x (3/2) = (71 * 3) / (2 * 2) = 213/4 minutes

So, Emma spent 213/4 minutes studying for her test.

To find out how many minutes Emma spent studying, we need to calculate 1 1/2 times the amount Sarah spent studying.

First, let's convert the mixed number 35 1/2 into an improper fraction.
35 1/2 = (2 * 35 + 1) / 2 = 71/2

Now we can calculate 1 1/2 times the amount Sarah spent studying:
(1 1/2) * (71/2) = 1 * (2 * 71 + 1) / 2 = (142 + 1) / 2 = 143/2

So, Emma spent 143/2 minutes studying for her test.

If we want to express the answer as a mixed number, we can divide 143 by 2:
143 ÷ 2 = 71 remainder 1

The quotient is 71, and the remainder 1 represents the remaining half.

Therefore, Emma spent a total of 71 1/2 minutes studying for her test.
