Question: Which of the following fraction is the largest ?

[A].

7

8

[B].

13

16

[C].

31

40

[D].

63

80

Answer: Option A

Explanation:

L.C.M. of 8, 16, 40 and 80 = 80.

7	=	70	;	13	=	65	;	31	=	62
8		80		16		80		40		80

Since,	70	>	65	>	63	>	62	, so	7	>	13	>	63	>	31
	80		80		80		80		8		16		80		40

So,	7	is the largest.
	8
