Mental Maths (Comparison of Fractions)

 Mental Maths (Comparison of Fractions) - Part 2

Contd to the post Mental Maths (Comparison of Fractions) - Part 1  ☚

Model 5 : 

• For a fraction Less than 1 :

• If the difference between the numerator and the denominator is same then the fraction with the larger values of numerator and denominator will be the largest. Have a look at the following example.

• Which of the following fractions is the largest?
• (31/37), (23/29), (17/23), (35/41), (13/19) 
• The difference between the numerator and the denominator of each fraction is 6.... So the fraction with the larger numerals i.e., 35/41 is the greatest and the fraction with smaller numerals i.e., 13/19 is the smallest.

• For a fraction Greater than 1 :

• If the difference between the numerator and denominator is same, then the fraction with the smaller values will be the largest.

• Which of the following fraction is largest ?
• (31/27), (43/39), (57/53), (27/23), (29/25)
• As the difference between the numerator and the denominator is same, the fraction with the smaller values i.e., 27/23 is the largest.

Model 6 : 

• Which of the following fractions is the largest?
• (15/17), (23/29), (31/34), (11/15)
• Comparing fractions 15/17 and 23/29
• The numerator of the fraction has increased from 15 to 23. i.e. 8/15 i.e. a little more than 50%.  The denominator of the fraction has increased from 17 to 29. i.e., 12/17 i.e., well over 50%. As the percentage increase in the numerator is less than the  percentage increase in the denominator, the fraction 15/17 > 23/29.
• Now compare 15/17 with 31/34
• As the change in the numerator is more than double (15 to 31), and the change in the denominator is exactly double, the fraction 15/17 < 31/34.
• Now compare 11/15 and 31/34
• The numerator has almost tripled from 11 to 31 whereas the denominator has just over doubled from 15 to 34. Since the increase in numerator is greater than the increase in the denominator, 31 /34 > 11/15.
• So, 31/34 is the largest fraction :)

Mental Maths (Comparison of Fractions)

 Mental Maths (Comparison of Fractions) - Part 1

You have to Compare the given fractions in a number of problems in Data Interpretation and Quantitative Ability. Let us study some of the common methods of identifying out the largest or smallest of a given set of fractions which are useful for Mental Maths. 

Model 1 :

When the numerators are same and the denominators are different, the fraction with the largest denominator is the smallest. Have a look at the following example.

• Which of the following fractions is the smallest?
• (3/5) , (3/7) , (3/13), (3/8)

• Here, 13 is the largest denominator, so, (3/13) is the smallest fraction. 5 is the smallest denominator, hence (3/5) is the largest fraction.
• Here logic is very simple, 
• Situation 1 : Assume that you are 5 Children in your family. Your Dad brought an Apple and mom cut it into 5 pieces and distributed among all the children including you. (1/5)
• Situation 2 : Assume that you are 8 Children in your family. Your Dad brought an Apple and mom cut it into 8 pieces and distributed among all the children including you. (1/8)
• In which Situation will you get the BIG Piece of the Apple??? ;). Obviously in the Situation 1. Thats it.........

Model 2 :

When the numerators are different and the denominators are same, the fraction with the largest numerator is the largest. Have a look at the following example. 

• Which of the following fractions is the smallest?
• (7/5) , (9/5), (4/5), (11/5)

• As 4 is the smallest numerator, the fraction 4/5 is the smallest.
• As 11 is the largest numerator, the fraction 11/5 is the largest.
• Here too logic is very simple,
• Situation 1 : Assume that you are 4 Children in your family. Your Dad brought 8 Apples and mom distributed them among all the children including you. (8/4)
• Situation 2 :  Assume that you are 4 Children in your family. Your Dad brought 12 Apples and mom distributed them among all the children including you. (12/4)
• In which situation will you get more apples? Obviously in the second. So, 12/4 is the Biggest.. Thats it ;)

Model 3 :

The fraction with the largest numerator and the smallest denominator is the largest.

• Which of the following fractions is the largest?
• (19/16), (24/11), (17/13), (21/14), (23/15)

• As 24 is the largest numerator and 11 is the smallest denominator, 24/11 is the largest fraction. 
• Logic??? Cutting the More fruits into Less pieces is more beneficial for you than cutting the Less fruits into More pieces :P

Model 4 : 

When the numerators of two fractions are unequal, we try and equate them by suitably cancelling factors or by suitably multilplying the numerators. Thereafter we compare the denominators as in Model 1. Have a look at the following examples.

• Which of  the following fractions is the largest?
• (64/328), (28/152), (36/176), (49/196)

• 64/328 = 32/164 = 16/82 = 8/41 this is approximately equal to 1/5
• Note : In these type of problems, approximate values will be enough. No need to get EXACT values.
• 25/152 = 14/76 = 7/38 this is approximately equal to 1/5.5
• 36/176 = 18/88 = 9/44 this is approximately equal to 1/5
• 49/196 = 7/28 = 1/4
• As all the numerators are 1 and the least denominator is 4, the fraction 49/196 is the largest
• Which of the following fractions is the largest?
• (71/181), (214/519), (429/1141)

• (71/181) = (71 X 6) / (181 X 6) = 426/1086
• (214/519) = (214 X 2) / (519 X 2) = 428/1038

• The numerators are now all ALMOST equal (426, 428 and 429). The smallest denominator is 1038. 
• So, the largest fraction must be 428/1038  that is 214/519 :)
