A sauce recipe uses 4 cans of tomatoes in every 212 quarts.

Burka [1]

Answer:

$1\frac{3}{5}\ cans$

Step-by-step explanation:

<u><em>The correct question is</em></u>

A sauce recipe uses 4 cans of tomatoes in every 2 1/2 quarts.

How many cans of tomatoes are used in each quart of the sauce?

Let

x ----> the number of cans of tomatoes

we know that

$2\frac{1}{2}\ quarts=\frac{2*2+1}{2}=\frac{5}{2}\ quarts$

using proportion

$\frac{4}{(5/2)}\frac{cans}{quarts}=\frac{x}{1}\frac{cans}{quart}\\\\x=4/(5/2)\\\\x=\frac{8}{5}\ cans$

Convert to mixed number

$\frac{8}{5}\ cans=\frac{5}{5}+\frac{3}{5}=1\frac{3}{5}\ cans$
