Take a strip and divide it into three equal parts and shade 1 part out of the

three equal parts as shown.

Here, total parts = 3; shaded part = 1; unshaded parts = 2
So, the shaded part is one-third of the whole strip, which means that 1 out of

the 3 parts is shaded.

1
The fraction for the shaded part is . It is read as one by three or one upon

three. 3

ONE-FOURTH OR QUARTER 4

When we divide an object into four equal parts, each part is called one-fourth

1
or quarter of the whole object. We write one-fourth or quarter as and read
4
it as one by four or one upon four.

Take a strip, divide it into four equal parts and shade 1 part out of the four
parts as shown.

4
Here, total parts = ; shaded part = 1; unshaded parts = 3
So, the shaded part is one-fourth or quarter of the whole strip, which means
4
that 1 out of parts is shaded.
1
The fraction for the shaded part is . It is read as one by four or one upon four.
