Question

Write each fraction as a percent :

a) 13 over 50
b) 3 over 5
c) 3 over 20
d) 127 over 100.​

Answer 1

To convert fractions to percents, the fraction is expressed with a denominator of 100 if possible, or converted to a decimal first. The fractions 13/50, 3/5, 3/20, and 127/100 convert to 26%, 60%, 15%, and 127% respectively.

Step-by-step explanation:

Converting Fractions to Percents

Converting fractions to percents involves expressing the fraction as a ratio to 100. To find the percent, you either convert the fraction to a decimal first and then to a percent, or directly use equivalent fractions to get the denominator to be 100. Let's apply this to the given fractions:

1. 13 over 50: We can multiply the numerator and denominator by 2 to get a denominator of 100, thus 13/50 = 26/100, which means the percent is 26%.
2. 3 over 5: Multiply both the numerator and denominator by 20 to get 3/5 = 60/100, hence the percent form is 60%.
3. 3 over 20: Here, we multiply by 5 to get 3/20 = 15/100, so the percentage is 15%.
4. 127 over 100: This fraction already has a denominator of 100, so it directly translates to 127%.

Remember, converting to a decimal is another valid method where you first divide the numerator by the denominator and then multiply the result by 100 to get the percent.
