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.
To find out how much time Lara spends doing stretching exercises, we need to find 2/5 of 1 3/4 hours.
First, we need to convert 1 3/4 hours to an improper fraction.
1 3/4 hours is equal to 7/4 hours.
Next, we need to multiply 7/4 hours by 2/5.
7/4 * 2/5 = (7*2)/(4*5) = 14/20.
Finally, we can simplify the fraction.
14/20 simplifies to 7/10.
Therefore, Lara spends 7/10 of an hour, or 42 minutes, doing stretching exercises.
