To find the time Lara spends doing stretching exercises, we multiply the total time (1 3/4 hours) by the fraction representing the time spent on stretching exercises (2/5).
1 3/4 * 2/5 = (7/4) * (2/5) = 14/20
To simplify this fraction, we can divide the numerator and denominator by their greatest common divisor, which is 2.
(14/2) / (20/2) = 7/10
Therefore, Lara spends 7/10 of an hour doing stretching exercises. Simplified, this is 0.7 hours.
