Question

What is 16.5% of 33?

Answer 1

5.445

Explanation:

`\bold{METHOD\ 1:}\\\\p\%=(p)/(100)\to16.5\%=(16.5)/(100)=(16.5\cdot10)/(100\cdot10)=(165)/(1000)=(33)/(200)\\\\16.5\%\ of\ 33=(33)/(200)\cdot33=(1089)/(200)=5.445`

`\bold{METHOD\ 2:}\\\\\begin{array}{ccc}100\%&-&33\\\\16.5\%&-&x\end{array}\qquad\text{cross multiply}\\\\\\100x=(16.5)(33)\\\\100x=544.5\qquad\text{divide both sides by 100}\\\\x=(544.5)/(100)\\\\x=5.445`
