Question

What is 30% of 8 cups?

Answer 1

30% of 8 cups is 2.4 cups

Explanation:

`\bold{METHOD\ 1:}\\\\p\%=(p)/(100)\\\\30\%=(30)/(100)=0.3\\\\30\%\ of\ 8\ cups\to0.3\cdot8\ cups=2.4\ cups`

`\bold{METHOD\ 2:}\\\\\begin{array}{ccc}100\%&-&8\ cups\\\\30\%&-&x\end{array}\qquad\text{cross multilpy}\\\\100x=(30)(8)\\\\100x=240\qquad\text{divide both sides by 100}\\\\(100x)/(100)=(240)/(100)\\\\x=2.4`
