10 minutes warm-up, 25 minutes lifting weights, 15 minutes treadmill.....so the entire workout is (10 + 25 + 15) = 50 minutes
the ratio of minutes lifting weights to total workout...
he lifted weights 25 minutes
the total workout was 50 minutes
so the ratio is : 25/50 which reduces to 1/2 or 1:2 or 1 to 2 <==
