• A. 5
• B. 2
• C. 6
• D. 21

Answer 1

Answer:

B. 2

The exact value of the expression is 2.

## Method 1: Fractional Equation

You can solve this by converting the percentages into fractions and simplifying each part.

1. Calculate the first part (20% of 5):

* "20%" means 20 out of 100: $\frac{20}{100}$

* "Of" means multiply: $\frac{20}{100} \times 5$

* Simplify the fraction: $\frac{1}{5} \times 5 = 1$

2. Calculate the second part (5% of 20):

* "5%" means 5 out of 100: $\frac{5}{100}$

* "Of" means multiply: $\frac{5}{100} \times 20$

* Simplify the fraction: $\frac{1}{20} \times 20 = 1$

3. Add the two results together:

* $1 + 1 = 2$
