Tyrone is converting StartFraction 45 Over 50 EndFraction to a percent. Which method should he use to find the percent?

Question

Divide the numerator and denominator of the fraction by 2.
Subtract 40 from the numerator and denominator of the fraction.
Multiply the numerator and the denominator of the fraction by 2.
Add 50 to the numerator and denominator of the fraction

Answer 1

To convert a fraction to a percent, Tyrone should use the method that involves dividing the numerator by the denominator and then multiplying by 100.

Given the fraction \( \frac{45}{50} \):

1. Divide the numerator by the denominator: \[ \frac{45}{50} = 0.9 \]

2. Multiply the result by 100 to convert it to a percent: \[ 0.9 \times 100 = 90% \]

None of the options Tyrone has suggested are correct for converting the fraction to a percent. Instead, he should simply divide the numerator by the denominator and multiply by 100.

So the best approach is simply to divide \( 45 \) by \( 50 \) and multiply by \( 100 \), which gives the correct percent of \( 90% \).
