faltersainse [42]

<em><u>Complete Question:</u></em>

A restaurant uses 4.375 pounds of cheese every 8 and 3/4 pizzas. At this rate how many pounds of cheese are used per pizza?

<em><u>Answer:</u></em>

0.5 pounds of cheese are used per pizza

<em><u>Solution:</u></em>

Given that,

A restaurant uses 4.375 pounds of cheese every 8 and 3/4 pizzas

Therefore,

$4.375\ pounds = 8\frac{3}{4}\ pizza \\\\4.375\ pounds = \frac{35}{4}\ pizza$

We have to find pounds used per pizza

Let "x" be the pounds used per pizza

Then,

$4.375\ pounds = \frac{35}{4}\ pizza \\\\x\ pounds = 1\ pizza$

By cross multiplying,

$4.375 \times 1 = x \times \frac{35}{4} \\\\x = 0.5$

Thus, 0.5 pounds of cheese are used per pizza
