Did you know that there are different types of fractions?
The two types that we are looking at are called unit fractions and non-unit fractions. Both unit and non-unit fractions show us how much of the whole we are talking about.
A unit fraction is a fraction where the numerator (the number on the top of the fraction) is 1. The denominator (on the bottom) can be any other whole number. A good way to remember it is by remembering that unit means 1!
Here are some examples of unit fractions: ½, ¼ and ¹⁄₁₀
Can you think of any other unit fractions?
A non-unit fraction is a fraction where the numerator is greater than 1. The denominator can be any whole number.
Here are some examples of non-unit fractions: ⅖, ⁷⁄₁₂ and ¾
Can you think of any other non-unit fractions?
Emma and Sophie shared a pizza that was cut into 6 pieces.
Sophie ate ⅙ of the pizza and Emma ate ⅚ of the pizza.
Which of these two fractions is the non-unit fraction?
Look carefully at the numerators. If it’s a non-unit fraction, we’re looking for a number that isn’t 1, so ⅚ is the non-unit fraction. That means ⅙ is a unit fraction.
Take a look at this rectangle that has been split into 10. Some of the squares are different colours.
- ¹⁄₁₀ squares is yellow.
- ⁴⁄₁₀ squares are orange.
- ⁵⁄₁₀ squares are red.
Which colour represents a unit fraction?
Let’s look at the numerators. Remember, unit means 1 so look for the fraction that has 1 as the numerator.
Yellow represents the unit fraction since it is ¹⁄₁₀ of the rectangle.
