Do you notice what these fractions have in common?
1/2, 1/3, 1/4, 1/6, and 1/8.
That's right!
They all have a numerator of 1.
A fraction whose numerator is 1 is called a unit fraction.
👉 A unit fraction is always just one part of the whole.
Take a look at these visual models, or drawings, for some unit fractions.
Let's look at an example.
What unit fraction is represented by the model? 👇🤔
1️⃣ First, count how many equal parts the model is divided into.
This is your denominator.
2️⃣ Next, count the number of filled-in parts.
This is your numerator.
Tip: Unit fractions only have one part that's shaded or colored.
The model above is divided into 8 equal parts.
So the denominator of the unit fraction is 8. 😁
How many parts of the model are colored? 🤔
Correct, 1 part! ✅
That means the numerator of the unit fraction is 1.
The unit fraction that's represented by the model is:
What unit fraction does the red apple in this group show?
There are 6 apples.
That means the denominator of the unit fraction is 6. 😁
How many of the apples are red? 🤔
That's right, 1 apple! ✅
That means the numerator of the unit fraction is 1. 😁
The unit fraction that represents the red apple in the group is:
Great! You just mastered unit fractions. 🎉
Now, complete the practice. 😺 You'll remember what you learned about unit fractions for longer.
