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