Answer:
6 7/8 pints
Step-by-step explanation:
The amount of water in a barrel decreases 9 5/8 pints in 7 weeks. The water decreases the same amount each week. What is the change in the amount of water in pints in the barrel in 12 weeks?
From the question, we know that:
7 weeks = 9 5/8 pints
12 weeks = x
Cross Multiply
7x = 12 × 9 5/8
x = 12 × 9 5/8/7
x =( 12 × 77/8 ) ÷ 7
x = 12 × 77/8 × 1/7
x = 12 × 11/8
x = 16 1/2 pints
The change in the amount of water in pints in the barrel in 12 weeks is calculated as:
16 1/2 pints - 9 5/8 pints
Lowest common denominator = 8
7 + (4 - 5/8)
7 + (-1/8)
= 6 7/8 pints
