Finding Fractions

Half (two quarters) of a Collection

Look at the given collection of balls.
1
Let us find of the collection of 10 balls.
2

We divide the collection into two equal parts by a
1
line as shown. Each part represents half ( ) of the collection.
2
1
So, 10 ÷ 2 = 5 or of 10 = 5.
2 To find half of a

Thus, half of 10 balls is 5 balls. collection, we
divide it by 2.
one-third of a Collection

Look at the given collection of balls. It has 12 balls.

1
Let us find of the given collection.
3
1
means 1 out of 3 equal parts.

1 To find one-third of a
So, of 12 or 12 ÷ 3 = 4. collection, we divide
3 it by 3.
Thus, one-third of 12 balls is 4 balls.
