Question

8 is what percent of 20?
a (\frac{20}{8}%)
b (60%)
c (\frac{8}{20}%)
d (40%)

Explanation:

Step1: Use the percentage formula

The formula for finding what percent \(a\) is of \(b\) is \(\frac{a}{b}\times100\%\). Here \(a = 8\) and \(b=20\).

Step2: Substitute the values into the formula

Substitute \(a = 8\) and \(b = 20\) into \(\frac{a}{b}\times100\%\), we get \(\frac{8}{20}\times100\%\).
Simplify \(\frac{8}{20}=\frac{2}{5}\), and \(\frac{2}{5}\times100\%=(2\times20)\% = 40\%\)

Answer:

D. \(40\%\)
