storchak [24]

Answer:

8 quarts

Step-by-step explanation:

<u>Step One: Figure out how much 40% is by making an equation:</u>

<em>Since we are looking for a percentage, we use cross multiplication to find X.</em>

\frac{x}{20} = \frac{40}{100}

<u>Step Two: multiply 20 by 40 to start cross multiplying:</u>

<em>20 times 40 is 800, so replace the 40 by 800 in the equation.</em>

\frac{x}{20} = \frac{800}{100}

<u>Step Three: divide 800 by 100, and we will have X:</u>

<em>800/100=8</em>

<em><u>X=8 aka 8 quarts</u></em>

I hope this helps!
