Sarah = 35 1/2 minutes
Emma = 1 1/2 * 35 1/2 minutes
First, let's convert 35 1/2 to a mixed number:
35 1/2 = 70/2 + 1/2 = 71/2
Now, let's calculate Emma's studying time:
Emma = 1 1/2 * 71/2
Emma = 3/2 * 71/2
Emma = 3/2 * 71/2
Emma = 213/2
Emma spent 213/2 minutes studying.
To express it as a mixed number, we divide 213 by 2:
213 ÷ 2 = 106 with a remainder of 1
So, Emma spent 106 and 1/2 minutes studying. Answer: \boxed{106\frac{1}{2}}.
your supposed to pick one of the answer choices given
I apologize for the confusion. In this case, the answer choice that matches the calculation is "106 1/2 minutes" or "106 and 1 half minutes".
