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.(1 point)

Answer 1

To find out how much time Lara spends doing stretching exercises, we need to multiply the total time she spends working out by the fraction she spends doing stretching exercises.

1 3/4 hours can be written as 7/4 hours.

So, Lara spends 2/5 * 7/4 hours doing stretching exercises.

Multiplying the fractions, we get:

(2 * 7) / (5 * 4) = 14/20

Simplifying the fraction, we get:

14/20 = 7/10

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