Chapter 13, Problem 13QC

To determine

To find: The quantity of water which was already in the can.

Answer to Problem 13QC

There was $\frac{5}{8}$ gallon of water already in the can.

Explanation of Solution

Given information:

Hannah finished filling a $\frac{7}{8}$ gallon watering can by pouring $\frac{1}{4}$ of a gallon of water into the can.

Calculation:

Total quantity of water in the can is $\frac{7}{8}$ gallon.

Hannah poured $\frac{1}{4}$ gallon of water to fulfil the can.

Then, quantity of water which was already in the can

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

Thus, $\frac{5}{8}$ gallon of water was already in the can.
