What is 33 percent of 400
Eduardwww [97]
<h2>QUESTION</h2>

What is 33% of 400?

<h2>ANSWER AND EXPLANATION</h2>

To find the percent of a number, you have to change the percent into a decimal or a fraction and multiply by the number.

<h3>DECIMAL</h3>

To change a percent into a decimal, remove the percent sign and move the decimal point 2 places to the left.

33 \% \rightarrow 0.33

Now that you have your decimal, multiply by 400:

0.33 \times 400 = 132

ANSWER = 132

<h3>FRACTION</h3>

To change a percent into a fraction, make the percent number as the numerator(top number) and 100 as the denominator(bottom number) since fractions are out of 100.

33 \% \rightarrow \frac{33}{100}

Now that you have your fraction, multiply by 400:

\frac{33}{100} \times 400 = \frac{13200}{100} \rightarrow 132

ANSWER = 132
