Question

1. what percent of 90 is 54?

Explanation:

Step1: Set up the proportion

Let the percentage be \( x \). We know that \( \frac{x}{100} \times 90 = 54 \), which can be rewritten as \( \frac{90x}{100}=54 \).

Step2: Solve for \( x \)

Multiply both sides by 100: \( 90x = 54\times100 \)
\( 90x = 5400 \)
Divide both sides by 90: \( x=\frac{5400}{90} \)
\( x = 60 \)

Answer:

60%
