Question

The sum of the two rational numbers is `(-2)/3`. If one of them is `(-8)/15` Find the other.

Answer 1

The sum of two rational number = `(-2)/3`

And, one of the numbers = `(-8)/15`

The other rational number

`= (-2)/3 - (-8)/15`

3	3, 15
5	1, 5
	1, 1

LCM of 3 and 15 = 15

`= (-2xx5)/(3xx5) + (8xx1)/(15xx1)`

(LCM of 3 and 15 = 15)

`= (-10+8)/15 = (-2)/15`
