Question

If 20% of a number equals 3, find 100% of that number.

Answer 1

To find the number based on the information given, we can set up the equation based on the percentage:

Let \( x \) be the number. According to the information provided,

\[
20\% \text{ of } x = 3
\]

This can be rewritten as:

\[
0.2x = 3
\]

To find \( x \), we can divide both sides of the equation by 0.2:

\[
x = \frac{3}{0.2}
\]

Calculating the division gives:

\[
x = \frac{3}{0.2} = 3 \div 0.2 = 3 \times \frac{10}{2} = 3 \times 5 = 15
\]

Thus, \( x = 15 \). Since we are asked for 100% of the number, we can conclude that:

\[
100\% \text{ of the number } = 15
\]

Therefore, the answer is:

\[
\boxed{15}
\]
