Which pair of fractions are proportional? a)36/54 and 6/9 b)6/7and 16/21 c) 21/36and 21/42 d) 14/35 and 21/42

Option A

are proportional.

Solution:

If two fractions are equal, than it is said to be in proportion.

Case 1:  

Consider option A

Given fractions are

Hence both the fractions are equal. So they are propotional.

Case 2:

Consider option 2

Given fractions cannot be simplified further. Also both the fractions are not equal. So they are not propotional.

Case 3:

Consider option 3

Given fractions are

Hence are not equal. Hence they are not propotional.

Case 4:

Consider option 4  

Given fractions are

Hence are not equal. Hence they are not propotional.
