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 the amount of time Lara spends doing stretching exercises, we need to calculate 2/5 of 1 3/4 hours.
1 3/4 = (4*1 + 3)/4 = 7/4
2/5 * 7/4 = 14/20 = 7/10
Therefore, Lara spends 7/10 of an hour doing stretching exercises.
