Answer:
1/6 (=0.1667)
Step-by-step explanation:
If we look just at weeks 2, 3 and 4:
Week 2: 40 regular + 6 overtime
Week 3: 40 regular + 10 overtime
Week 4: 40 regular + 4 overtime
Total number of regular hours = 40 + 40 + 40 = 120
Total number of overtime hours = 6 + 10 + 4 = 20
number of overtime hours as a fraction of number of regular hours
= number of overtime hours / number of regular hours
= 20 / 120 (simplify by dividing numerator and denominator by 20)
= 1/6 (=0.1667)
