Question

What is 7% of $1.50​

Answer 1

Answer:

0.105

0.11 if you are expected to round to nearest cent.

Step-by-step explanation:

"of" should be thought of as times.

So you are doing:

$7\% \cdot 1.50$

7% is the same as .07; you could just replace percent with times 1/100 if you don't know. Like this 7%=7*1/100=7/100=.07.

$.07 \cdot 1.50$

When putting this into the calculator you get 0.105.

Answer 2

Answer:

7% of %1.50 is equal to $0.105 ≈ $0.11

Step-by-step explanation:

METHOD 1:

$\begin{array}{ccc}100\%&-&\ 1.50\\7\%&-&\ x\end{array}\qquad\text{cross multiply}\\\\100x=(7)(1.50)\\\\100x=10.50\qquad\text{divide both sides by 100}\\\\\dfrac{100x}{100}={\dfrac{10.5}{100}\\\\x=0.105$

METHOD 2:

$p\%=\dfrac{p}{100}\to7\%=\dfrac{7}{100}=0.07\\\\7\%\ of\ \ 1.50\ is\ equal\ to\ 0.07\ of\ \ 1.50:\\\\0.07\cdot\ 1.50=\ 0.105$
