Comparison of ratio or fraction is most frequently asked question in competitive exams. To find smallest or biggest of the given fraction, two approaches are to be used.

Method 1: Make denominator of the given fractions same.

Make denominator of the given fractions same.

To do it, Take LCM of 4, 6, 8, 10.

LCM of 4, 6, 8, 10 is 120.

So try to make denominator as 120.

(Here We are Multiplying and Dividing by same amount so we are not changing the value of the fraction.)

Now we can easily compare these fractions.

Method 2: Make numerator of the given fractions same.

Make numerator of the given fractions same.

To do it, Take LCM of 3, 5, 7, 11.

LCM of 3, 5, 7, 11 is 1155.

So try to make numerator as 1155.

(Here We are Multiplying and Dividing by same amount so we are not changing the value of the fraction.)

Now we can easily compare these fractions.

The number which has smallest denominator is the biggest number and vise-versa.
