CPM Homework Help : MC1 Problem 9-152

These volume measures are all equivalent:

$1$ gallon

$4$ quarts

$8$ pints

$16$ cups

Rewrite each of the following volume measures using at least two different units. For example, $2$ gallons can be rewritten as $8$ quarts, $16$ pints, or $32$ cups.

$\frac { 1 } { 2 }$ gallon
Hint (a):
$\frac{4\text{ quarts}}{1\text{ gallon}}=\frac{x\text{ quarts}}{\frac{1}{2}\text{ gallon}}$
Partial Answer (a):
$x = 2$ quarts

2 pints
Hint (b):
$2$ pints is a quarter of $8$ pints, or a quarter of one gallon. How many quarts is that? How many cups?

3 cups
Hint (c):
You can set up proportions as shown in part (a) or use logic, as shown in part (b). Which way do you prefer?
