Question

If 4 out of 8 pineapples are rotten, then what percent of the total pineapples are rotten?

• A. 20%
• B. 25%
• C. 40%
• D. 50%

Answer 1

The correct option is D 50%

Fraction of rotten pineapples = $\frac{4}{8}$
Here, we see that the denominator is not a hundred.
Percentages are numerators of fractions with denominator 100.
Hence, we need to convert this fraction to an equivalent fraction with denominator 100.
$\frac{4}{8}=\frac{4}{8}\times \frac{100}{100}=\frac{400}{8}\times \frac{1}{100}=\frac{50}{100}=50\%$
