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
A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.
hope this helps!
All you would have to do is look at the 2 in the place of the thousands which equals 2000, then look at the 2 that is in the place of the tens, which equals 20, so (this might get complicated) 2000/20 is... (If you need more help just tell me)
