The picture shows four fractions , 1/2, 2/4, 3/6, and 4/8. These are equivalent fractions. A fraction without a common factor between the numerator and the denominator is the simplest form of the equivalent fractions. The fraction 3/6 is given. what would be the approach to find the simplest form of the fraction?

• divide the numerator and denominator by any common factors
• divide the numerator and denominator by any common factors
• multiply the numerator and denominator such that they are common multiple

The answer is 'divide the numerator and denominator by the highest common factor (HCF) or the greatest common divisor (GCD). '

A fraction without a common factor between the numerator and the denominator is the simplest form of the equivalent fractions.

Finding Simplest form of a fraction: Given a fraction p/q, to find the simplest form of the fraction
find the highest common factor i such that p = l xx i and q = m xx i. Then the simplest form is l/m.'

Solved Exercise Problem:

What is the simplest form of 35/45?

• 9/9
• 7/9
• 7/9
• 5/5
• 9/7

The answer is '7/9'. The HCF of numerator and denominator is 5 which is canceled in both numerator and denominator. 35/45 = (7 xx 5)/(9 xx 5) = 7/9
