Question

The sum of two rational numbers is `(-3)/8`. If one of them is `3/16` find the other,

Answer 1

Sum of two numbers = `(-3)/8`

One number = `3/16`

∴ Second number = `(-3)/8 - 3/16`

2	8,16
2	4, 8
2	2, 4
2	1, 2
	1, 1

 

 

 

 

 

L.C.M. of 8 and 16 = 2 × 2 × 2 × 2 = 16

`= (- 3 xx 2)/(8 xx 2) - (3 xx 1)/(16 xx 1)`

(∵ L.C.M. of 8 and 16 = 16)

`= (- 6 -3)/16 = (- 9)/16`

∴ Second number = `(- 9)/16`
