Q. Which of the following options have the same value as

15 \%

of

20

?

\newline

Choose

3

answers:

\newline

A

\frac{3}{20} \cdot 20

\newline

B

15 \cdot 20

\newline

c

0.15 \cdot 20

\newline

D

\frac{15}{100} \cdot 20

\newline

E

15 \cdot 0.02

Convert to Decimal and Multiply: To find $15\%$ of $20$ , we convert the percentage to a decimal and multiply by $20$ . $\newline$ Calculation: $15\%$ of $20 = 0.15 \times 20 = 3$
Option A Simplification: Option A: $(\frac{3}{20}) \times 20$ simplifies to $3$ , since the $20$ s cancel out. $\newline$ Calculation: $(\frac{3}{20}) \times 20 = 3$
Multiplication Not Percentage: Option B: $15 \times 20$ is not a percentage of $20$ , it's a multiplication of $15$ by $20$ . $\newline$ Calculation: $15 \times 20 = 300$
Decimal Form Calculation: Option C: $0.15 \times 20$ is the decimal form of $15\%$ multiplied by $20$ . $\newline$ Calculation: $0.15 \times 20 = 3$
Fraction Form Calculation: Option D: $(\frac{15}{100}) \times 20$ is the fraction form of $15\%$ multiplied by $20$ . $\newline$ Calculation: $(\frac{15}{100}) \times 20 = (\frac{15 \times 20}{100}) = \frac{300}{100} = 3$
Not $15$ % of $20$ : Option E: $15 \times 0.02$ is not $15\%$ of $20$ , it's $15$ times $0.02$ . $\newline$ Calculation: $15 \times 0.02 = 0.3$
