Jordan worked out at a gym for 2 hours. his workout consisted of stretching for 21 minutes, jogging for 45 minutes, and lifting weights for the remaining amount of time. what percentage of jordan’s workout was spent lifting weights?

2 hours is equivalent to 120 minutes.  21+45 is 66.  So he spent 66 minutes not lifting weights, and 54 minutes lifting weights.  54/120 would be equivalent to 45%.  So he spent 45% of his workout lifting weights.  Hope this helps!!
