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 the time Lara spends doing stretching exercises, we can multiply the total time she spends working out by the fraction of time she spends doing stretching exercises: 1 3/4 × 2/5 = (7/4) × (2/5) = (14/20) = 7/10
Thus, Lara spends 7/10 of an hour, or 42 minutes, doing stretching exercises. Answer: \boxed{42}.
