Solution for fraction 21/42 to simplified form

Follow these easy steps to simplify 21/42-

Given fraction is => 21/42

21 = Numerator

42 = Denominator

• Greatest Common Factor(GCF) of the numerator and the denominator :
GCF(21,42) = 21


• The greatest common factor of the numerator[21] and the denominator[42] is 21.
• Now divide the numerator[21] and the denominator[42] by 21.
=> 21 ÷ 21/42 ÷ 21 = 1/2
