first, set up a proportion. 16.8/48 = x/100.

then cross multiply. 16.8 * 100. the answer to this is 1680 (take the decimal point and move it 2 places to the right).

lastly, divide. Take 1680 and divide it with 48.

your answer is 35%

Answer:

35%

Explanation:

Let
x = the percentage

Set up the proportion:


(16.8)/(48)=(x)/(100)

Cross multiply:


\implies 16.8 \cdot 100=x \cdot 48


\implies 1680=48x

Divide both sides by 48:


\implies (1680)/(48)=(48x)/(48)


\implies 35=x

Therefore, the solution is 35%
