Lara spends 1 3/4 hours working out. She spends 2/5 of the time doing stretching exercises. How much time does she spend doing stretching exercises? Write the answer in simplest form.

Answer 1

To find out how much time Lara spends doing stretching exercises, we need to find 2/5 of 1 3/4 hours.

First, we need to convert 1 3/4 hours to an improper fraction.
1 3/4 hours is equal to 7/4 hours.

Next, we need to multiply 7/4 hours by 2/5.
7/4 * 2/5 = (7*2)/(4*5) = 14/20.

Finally, we can simplify the fraction.
14/20 simplifies to 7/10.

Therefore, Lara spends 7/10 of an hour, or 42 minutes, doing stretching exercises.
