how do you convert fractions to decimals and percents
fraction to decimal: divide numerator by denominator. ex. 1/2=.5
decimals to percents: multiply decimal by 100. ex. .5x100=50
To convert a fraction to a decimal, you can use long division or a calculator. Here's how to do it manually:
1. Divide the numerator (the top number) by the denominator (the bottom number).
2. Keep dividing until you either get a repeating or terminating decimal.
For example, let's convert the fraction 3/4 to a decimal:
1. Divide 3 by 4: 3 ÷ 4 = 0.75
Therefore, 3/4 as a decimal is 0.75.
To convert a decimal to a percent, you multiply the decimal by 100 and add the percent sign (%). Here's how to do it:
1. Multiply the decimal by 100.
2. Place the percent sign (%) at the end.
For example, let's convert the decimal 0.75 to a percent:
1. Multiply 0.75 by 100: 0.75 × 100 = 75
Therefore, 0.75 as a percent is 75%.
To summarize:
- To convert a fraction to a decimal, divide the numerator by the denominator.
- To convert a decimal to a percent, multiply by 100 and add the percent sign (%).
