Question 1
Run laps = 2/3
Worked out in the room = 1/4
Team ran laps - Team worked out = 2/3 - 1/4 = (4 * 2 - 3 * 1)/(4 * 3) = 5/12
QUestion 2
CD use = 1/2
Savings = 1/3
Total utilization = 1/2 + 1/3 = (3 + 2)/(3 *2) = 5/6
Question 3
Total pack of construction paper = 8/9
Total papers used to make airplanes = 1/5 of total pack of construction paper
Fraction of original pack used to make airplanes = 8/9 * 1/5 = 8 / (9 * 5) = 8/45
Question 4
Logan sold = 7/8
Nathan sold = 6/7
Logan sold - Nathan sold = 7/8 - 6/7 = (7 * 7 - 8 * 6)/ (8 * 7) = 1/56
Question 5
Total nails of 1/2 pound = 8
Total nails of 3/8 pounds = 16
Total weight = 1/2 + 3/8 = (8* 1 + 3 * 2)/16 = 7/8 pound
Question 6
Total planted soyabean = 4/5
Total soyabean picked = 5/6 of total planted soyabean
What fraction was picked that day = (4/5) * (5/6) = 4/6 = 2/3
