Methods for Converting Fractions to Decimals
Convert fraction to an equivalent fraction with a denominator that is a power of ten before converting to a decimal.

1/2 = 5/10 = 0.5

3/20 = 15/100 = 0.15

1/8 = 125/1000 = 0.125

When proper/improper fractions have different numerators and denominators, the decimal equivalent of each can be calculated by dividing the numerator by the denominator.

3/4 = 0.75

3/8 = 0.375

4/15 = 0.0666...

Complete the numerator divided by the denominator calculation with a calculator.
