Evaluate each of the following: (i)(-5)...

Evaluate each of the following: (i)`(-5)/(14)-2/7` (ii) `(13)/(15)-(12)/(25)` (iii) `(-6)/(13)-(-7)/(13)`

Text Solution

Verified by Experts

(i)Evaluating: `(-5)/14-2/7`
`=-5/14-2/7`
Taking LCM, we get the LCM as `14`
`=(-5-4)/14`
`=-9/14`
We get the answer as `-9/14`.

(ii)Evaluating: `13/15-12/25`
`=13/15-12/25`
Taking LCM, we get the LCM as `75`
`=(65-36)/75`
`=29/75`
We get the answer as `29/75`.

(iii)Evaluating: `(-6)/13-(-7)/13`
`=-6/13+7/13`
Taking LCM, we get the LCM as `13`
`=(-6+7)/13`
`=1/13`
We get the answer as `1/13`.
