SimpleSt Form (loweSt termS) oF a Fraction

When the numerator and denominator of a fraction have no common factors other
than 1, then the fraction is said to be in its simplest form.

Example 1: Is 18 in its simplest form? Think Tank
21
Solution: Factors of numerator 18 are 1, 2, 3, 6, State True or False.

9 and 18. 1. 2 pieces of 1 make half.
Factors of denominator 21 are 1, 3, 7 6 4
and 21. 2. Sumit has read 5 of his book
Here the common factors of 18 and 21 and Tushar has read 8 of

are 1 and 3. 10
Thus, 18 is not in its simplest form. the same book. Sumit has
read more pages than Tushar.
