9% of 100 is what?
0.9

0.09

Explanation:

First Question (Fraction to Percent):

Step1: Recall fraction to percent rule

To convert a fraction to a percent, we multiply the fraction by 100 (and add the % symbol). For example, $\frac{1}{2} \times 100 = 50\%$.

Step2: Evaluate options

Multiplying by 1 leaves the fraction unchanged. Multiplying by 1000 or 10 doesn't give the percent form. Only multiplying by 100 converts the fraction to a percent.

Step1: Recall percent calculation

"Of" in percent problems means multiplication. So, 9% of 100 is calculated as $9\% \times 100$.

Step2: Convert percent to decimal

$9\% = \frac{9}{100} = 0.09$.

Step3: Multiply

$0.09 \times 100 = 9$.

Answer:

100 (the option with "100")
