To find the fraction of an hour Joseph spent lifting weights, we need to multiply the total time Joseph spent working out (3/4 hour) by the fraction of that time he spent lifting weights (2/3).
First, let's find the time Joseph spent lifting weights. We can multiply the total time spent (3/4 hour) by the fraction of that time spent lifting weights (2/3):
(3/4) * (2/3) = (3 * 2) / (4 * 3) = 6/12 = 1/2
Therefore, Joseph spent 1/2 hour (or half an hour) lifting weights.
