Step 1: Add all the fractions given:
2/5 + 3/20 + 1/3 = 53/60
Step 2: Subtract that answer from 1:
1 - 53/60 = 7/60
Step 3: Find out total time:
7/60x = 42
x=360
Step 4: Find time spent in social science:
360 * 3/20 = 54
2/5 + 3/20 + 1/3 = 53/60
Step 2: Subtract that answer from 1:
1 - 53/60 = 7/60
Step 3: Find out total time:
7/60x = 42
x=360
Step 4: Find time spent in social science:
360 * 3/20 = 54
