[AI-generated answer — Bot GPT 3.5]

To find the amount of time Lara spends doing stretching exercises, you need to multiply the total time she spends working out (1 3/4 hours) by the fraction representing the proportion of time spent on stretching exercises (2/5).

1 3/4 hours = 7/4 hours
7/4 hours * 2/5 = (7*2)/(4*5) = 14/20

To simplify 14/20, you can divide both the numerator and the denominator by their greatest common divisor, which is 2.
14/20 = (14/2)/(20/2) = 7/10

Therefore, Lara spends 7/10 of an hour, or 42 minutes, doing stretching exercises.
