Question

fill in the missing number.
□% of 80 = 20
submit

Explanation:

Step1: Let the missing percentage be \( x \).

We can write the equation as \( \frac{x}{100} \times 80 = 20 \).

Step2: Solve for \( x \).

First, simplify the left side: \( \frac{80x}{100}=20 \).
Multiply both sides by 100: \( 80x = 20\times100 \).
So, \( 80x = 2000 \).
Then divide both sides by 80: \( x=\frac{2000}{80} \).
Calculate \( \frac{2000}{80}=25 \).

Answer:

25
