Unit Fractions

A unit fraction has 1 on top — it shows ONE equal part of a whole!

A FRACTION names equal parts of a whole. A UNIT FRACTION always has 1 as the numerator (top number). It describes exactly one of the equal parts the whole was divided into.

📐

Numerator = number of parts we have. Denominator = total equal parts the whole is split into.

Unit fractions shown as parts of a circle:

1/2 (half)1/3 (one-third)1/4 (one-quarter)1/6 (one-sixth)

The larger the denominator, the SMALLER each piece — more cuts means tinier slices!

🍕Slicing a pizza
Cut a pizza into 4 equal slices.
Each slice is 1/4 of the pizza.

If you cut it into 8 equal slices,
each slice is 1/8 — smaller pieces!
💡

Remember This!

When comparing unit fractions, the BIGGER the denominator, the SMALLER the piece. 1/8 is smaller than 1/3 because you cut the pizza into more (smaller) slices.

✏️ Try It!

A sandwich is cut into 3 equal parts. What fraction names one of those parts?
