Question

What rational number should be added to `- 3/16` to get `11/24`

Answer 1

Sum of two numbers = `11/24`

One number = `- 3/16`

∴ The required number = `11/24 - ((-3)/16) => 11/24 + 3/16`

2	24,16
2	12, 8
2	6, 4
2	3, 2
3	3, 1
	1

 

 

 

 

 

 

 

L.C.M. of 16 and 24 = 2 × 2 × 2 × 2 × 3 = 48

(∵ L.C.M. of 24, 16 = 48)

`= (11 xx 2)/(24 xx 2) - (3 xx 3)/(16 xx 3)`

 

`= (22 + 9)/48 = 31/48`
