Simplest Form of a Fraction
Given the fraction
How do we do it?
A fraction is said to be in the simplest (or lowest) form if its numerator and denominator have no common factor except 1.
The shortest way to find the equivalent fraction in the simplest form is to find the HCF of the numerator and denominator, and then divide both of them by the HCF.
Let's try the more examples.
Try these
1. Write the simplest form of :
- It can be observed that
is the highest common factor of 15 and 75. - Divide the numerator and denominator by the highest common factor 15.
- Hence, we get the fraction is
.
- It can be observed that
is the highest common factor of 16 and 72. - Divide the numerator and denominator by the common factor 8.
- Hence, we get the fraction is
.
- It can be observed that
is the highest common factor of 17 and 51. - Divide the numerator and denominator by the common factor 17.
- Therefore, we get the fraction is
.
