Equal parts

There are 3 pictures with 2 figures given in each. Observe the figures and note your
observation.

Observation

The parts of a whole of the same size are called equal parts.

Rani and Kavita had a sheet of paper. They decided to share it equally.
Rani made 2 parts as shown.

Are the parts made by Rani equal? Why or why not?

No, they are not equal because the second part is larger than the first.

Now, this time Kavita made 2 parts as shown. Are they equal?
Yes, Kavita has made equal parts.

Let us see various equal parts of circles. They are called Fraction Discs.

Here, the whole circle is divided equally into 2, 3, 4, 5, 6, 8, 10 and 12 parts.

Keep in Mind

1
When a whole is divided into 2 equal parts, each part is (half). That means, 2 halves
2
make a whole. Similarly, 3 one-thirds, 4 one-fourths (quarters), 5 one-fifths, ... also
make a whole.
