Solved Example on Like Fractions
Ques: Choose the group of like fractions from the following:
I. 3/13, 6/13 , 10/13
II. 7/12 , 5/10 , 4/11
III. 1/9 , 1/7 , 1/10
IV. 2/9 , 4/5 , 1/9
Choices:
A. I onlyB. IV only
C. III only
D. II, III only
Correct Answer: A
Solution:

Step 1: Like fractions have the same denominators.
Step 2: All the three fractions in I have the same denominator 13. So, the fractions in I are like fractions.
Step 3: The denominators of all the three fractions in II have different denominators (i.e., 12, 10, and 11). So, the fractions in II are unlike fractions.
Step 4: The denominators of all the three fractions in III have the different denominators (such as 9, 7, and 10). So, the fractions in III are unlike fractions.
Step 5: The denominators of all the three fractions in IV are 9, 5, and 9. As the denominators of two of the fractions (2/9 and 1/9) are the same and the denominator of the other fraction is not the same like the other two fractions in the group, the fractions in IV are unlike fractions.
Step 6: So, the fractions in the group I are like fractions.
