Chapter 13, Problem 13QC

To determine

To calculate: To find how much water was already in the can

Answer to Problem 13QC

The amount of water already in watering can is $\frac{5}{8}$

Explanation of Solution

Given information: H finished filling a $\frac{7}{8}$ gallon watering can by pouring $\frac{1}{4}$ of a gallon of water into the can

Calculation:

Amount of water that is poured in watering can $=\frac{1}{4}$

Also, given that H finished filling a $\frac{7}{8}$ gallon watering

Thus, amount of water already in watering can is calculated as follow:

  $\begin{array}{l}A=\frac{7}{8}-\frac{1}{4}\\ A=\frac{7-2}{8}\\ A=\frac{5}{8}\end{array}$

Conclusion:

Hence, amount of water already in watering can is $\frac{5}{8}$
