## McGraw-Hill My Math Grade 5 Answer Key Chapter 11 Lesson 7 Convert Customary Units of Capacity

Capacity is the measure of how much a container can hold. Just like length and weight, the smaller the unit you use to measure capacity, the more precise the measurement.

**Math in My World**

**Example 1**

Sondra tries to drink 9 cups of water each day. How many fluid ounces of water are 9 cups?

Convert 9 cups to fluid ounces.

Since 1 cup = 8 fluid ounces, multiply 9 by 8.

So, 9 cups = ____________ fluid ounces.

Answer:

1 cup to fluid ounces = 8 fluid ounces

9 cups equal to 72 fluid ounces.

**Example 2**

How many quarts can be made from 7 pints?

Since 2 pints = ____________ quart, divide 7 by ____________.

The remainder ____________ means there is ____________ pint left over.

The fraction of a quart is ____________.

So, 7 pints = ____________ quarts ____________ pint, 3\(\frac{1}{2}\) quarts, or 3.5 quarts.

Answer:

since 2 pints = 1 quart, divide 7 by 2

The remainder 1 means there is 1 pint left over.

The fraction of a quart is 1/2.

therefore, 7 pints = 3 quarts 1 pint, 3 1/2 quarts or 3.5 quarts.
