Frequently asked questions
How do you convert a fraction to a decimal?
Divide the numerator (top number) by the denominator (bottom number). For example, 3/8 = 3 ÷ 8 = 0.375.
How do I convert a mixed number like 2 3/8?
Convert the fraction part and add it to the whole number: 2 + 3÷8 = 2 + 0.375 = 2.375. Enter the whole number in the first box above.
