Verify commutativity of addition of rational numbers for each of the following pairs of rational number :
(i)`(-3)/5 `and `(-2)/(-15)`

Explanation

Verify commutativity of addition of rational numbers for each of the following pairs of rational number :
`(-3)/5` and `(-2)/(-15)`
Commutativity of addition of rational number
`a/b+c/d=c/d+a/b`
`(-3)/5+2/15`
`=>-3/5+2/15=2/15+(-3)/5`
Taking `15` as LCM of `5` and `15`
`=>(-3xx3+2xx1)/(15)=(2xx1-3xx3)/(15)`
`=>(-9+2)/(15)=(2-9)/(15)`
`=>-7/15=-7/15`
Hence Verified.
