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 representing the proportion of time spent doing stretching exercises.
1 3/4 hours can also be written as 7/4 hours.
So, the time Lara spends doing stretching exercises is 7/4 * 2/5 = 14/20 = 7/10 hours.
Therefore, Lara spends 7/10 hours doing stretching exercises.
