if 20% of A equal to B then b percent of 20 equal to

We are given that 20% of \( A \) is equal to \( B \), which can be written as:

\[
\frac{20}{100} \times A = B
\]

Now, we are asked to find what \( B \% \) of 20 is equal to. This can be written as:

\[
\frac{B}{100} \times 20
\]

Substituting \( B = \frac{20}{100} \times A \) into the equation:

\[
\frac{\left( \frac{20}{100} \times A \right)}{100} \times 20
\]

Simplifying:

\[
\frac{20 \times A}{100} \times \frac{20}{100} = \frac{20^2 \times A}{100^2} = \frac{400 \times A}{10,000} = \frac{A}{25}
\]

So, \( B \% \) of 20 is equal to \( \frac{A}{25} \).

2. If 30% of \( A \) equals \( B \), what is \( B \% \) of 30?
3. How do you find the percentage of one number in terms of another?
4. If \( B = \frac{50}{100} \times A \), what is \( B \% \) of 50?
5. How does the relationship between \( A \), \( B \), and percentages change if we double \( A \)?

**Tip**: When solving percentage problems, always express the percentages as fractions or decimals to simplify the calculations.
