Best Answer

Divide the top number by the bottom number. Example: 1/4 = 1 divided by 4 = 0.25

Vocabulary used in the answer:

  • Numerator - The number above the line in a fraction.
  • Denominator - The number below the line in a fraction.
  • Quotient - The answer to a division problem.

Another way to do it, is that if the denominator is a factor of 100 then this method will be easier. First, you do 100 divided by the denominator. Then, you multiply the numerator by the quotient. Then put a decimal point in front of all the numbers. That would also give you a decimal.

Example:

1/5 = .20

100 divided by 5 equals 20

20 x 1 = 20

20 --> .20
The / sign in the fraction is actually the same as a divide sign. Divide the numerator (top) by the denominator (bottom) and you will end up with your decimal.

Example:

2/4 = 2 divided by 4 = 0.5

3/2 = 3 divided by 2 = 1.5

Example: Let's say you have the decimal 0.25, which is read as 25 one-hundredths. You can convert this to the fraction 25/100, and then simplify to 1/4.

Do the division. The line in a fraction can be read as "divided by."

3/4 = 3 divided by 4 = 0.75
