Case 1:

If the denominators are same then we can decide that the fraction which is having the greater numerator is greater.

Case 2:

If the denominators are different then we have to convert each fraction into equivalent fraction with the common denominator.

To make the denominator same we have to apply the concept LCM.

Comparing numerator 6 is greater than 5 hence 3/5 > ½

Multiplying fractions

  1. Multiply the numerators and put in the numerator of the result
  2. Multiply the denominators and put in the denominator of the result

  • To subtract two fractions, they also must have a Common Denominator

First make denominators same as done in addition then subtract

  • Improper fractions have bigger numerator and small denominator
  • Fractions having same denominator are called like fractions.
  • Fractions having different denominator are called unlike fractions.
