How much is 4/3, in wholes and pieces?
Today you'll discover
- when a product is more than one whole
- how to write 4/3 another way
- how to find the wholes inside a fraction
Think first4 × 1/3 = 4/3, laid end to end
4/3 is how many wholes, and how much more?
Decide first, then press Next. Find each full whole, then what is left.
Four pieces of one third, counted 1/3 to 4/3, fill one bar marked = 1 whole and start a dashed second bar marked 1/3 of one. Then the sentence 4 × 1/3 = 4/3 = 1 1/3. The last step shows seven halves.

The big idea
4/3 is more than one whole: 3 thirds make 1 whole, so 4/3 = 1 1/3.
Compare them4/3 is an improper fraction: the top is bigger than the bottom. 1 1/3 is a mixed number: a whole number and a fraction. Same amount.
More of them5 × 1/4 = 5/4 = 1 1/4. 7 × 1/3 = 7/3 = 2 1/3. 7 × 1/2 = 7/2 = 3 1/2.
Key words
- improper fraction
- a fraction whose top number is the same as or bigger than its bottom number, like 4/3
- mixed number
- a whole number and a fraction together, like 1 1/3
