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 workout time by the fraction of time she spends doing stretching exercises.
1 3/4 hours can also be written as 7/4 hours.
So, Lara spends 7/4 * 2/5 = 14/20 hours doing stretching exercises.
Simplifying the fraction 14/20, we get the final answer:
14/20 = 7/10
Therefore, Lara spends 7/10 of an hour or 42 minutes doing stretching exercises.
