QUESTION
What is 45% of 36 feet?
ANSWER AND EXPLANATION
To find the percent of a number, you have to change the percent into a decimal or a fraction and multiply by the number.
DECIMAL
To change a percent into a decimal, remove the percent sign and move the decimal point 2 places to the left.
[tex]45 \% \rightarrow 0.45[/tex]
Now that you have your decimal, multiply by 36:
[tex]0.45 \times 36 = 16.2[/tex]
ANSWER = 16.2 feet
FRACTION
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.
[tex]45 \% \rightarrow \frac{45}{100}[/tex]
Now that you have your fraction, multiply by 36:
[tex]\frac{45}{100} \times 36 = \frac{1620}{100} \rightarrow 16.2[/tex]
ANSWER = 16.2 feet
