Writing fractions in words helps students see that fractions are numbers that count parts, just like 4 apples or 4 tens. Denominators are 2, 3, 4, 5, 6, 8, 10, and 12.

Worked Examples

Worked Example 1

Three Ways to Write a Fraction

Write 38 in word form and in numeral-word form.
  1. 1The numerator is 3 and the denominator is 8, so the parts are eighths.
  2. 2Word form: three-eighths.
  3. 3Numeral-word form: 3 eighths.
Answer: three-eighths; 3 eighths

Worked Example 2

Word Form to Standard Form

Write seven-fifths in standard form.
  1. 1"Fifths" tells the denominator: 5.
  2. 2"Seven" tells how many fifths: 7.
Answer: 75

Common Mistakes to Watch For

Naming the denominator like a counting number

Wrong:26 is "two-sixes"

The parts are called sixths: 26 is two-sixths.

Switching the numerator and denominator

Wrong:five-halves = 25

"Halves" is the denominator (2) and "five" is the numerator: five-halves is 52.

Helpful Math Tip

Read fractions aloud whenever you see them (in recipes, on rulers, on measuring cups) and have your child write them each way.
