A leaky faucet wastes about 1/2 gallon of water every day. how long, in days, will it take for 15 2/5 gallons to be wasted?
The leaky faucet wastes 1/2 gallon of water every day.
To find the number of days it takes for 15 2/5 gallons to be wasted, we need to divide 15 2/5 by 1/2.
Convert the mixed number 15 2/5 to an improper fraction:
15 2/5 = (5 * 15 + 2) / 5 = 77/5
Divide 77/5 by 1/2:
(77/5) / (1/2) = 77/5 * 2/1 = (77 * 2) / (5 * 1) = 154/5
To find the number of days, we divide the total amount of water wasted by the amount wasted per day:
154/5 / 1/2 = 154/5 * 2/1 = (154 * 2) / (5 * 1) = 308/5 = 61.6
Therefore, it will take 61.6 days for 15 2/5 gallons to be wasted.
