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)
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.
