## What are Fractions?

Fractions are the numbers used to represent smaller pieces of a whole. Let us understand with the help of an example.

Harish and Haritha bought a pizza together. The pizza was cut into 12 slices. Harish had 7 slices

out of the 12 slices. So we can say Harish had 7

12

of the entire pizza. Haritha ate the remaining 5

slices out of the 12 slices. So Haritha had 5

12

parts of the entire pizza. Here, 7

12

and 5

12

are known

as fractions.

**Vinculum:**In a fraction, the horizontal line that separates the upper and lower number is known as the Vinculum.**Numerator:**The number above the vinculum is known as the Numerator.**Denominator:**The number below the vinculum is known as the Denominator.
