Question

Which of the following ratio is greater ?

`5/2 : 15/4` and `5/3 : 11/6`

Sum

Solution

`5/2 : 15/4` and `5/3 : 11/6`


`5/2 : 15/4 = 5/2 xx 4/15 = 2/3`


`5/3 : 11/6 = 5/3 xx 6/11 = 10/11`


`2/3 : 10/11`

⇒ 2 x 11 < 3 x 10 

⇒ 22 < 30 

⇒ 2: 3 < 10 : 11 

⇒ `5/2 : 15/4 < 5/3 : 11/6`

`5/3 : 11/6`  is greater.
