divide the sum of 65/12 and 12/7 by their difference

First of all v find the sum . 65/12 + 12/7 . Since they have different denominators , v find their LCM = 84

Therefore , 65/12 = 455/84

12/7=144/84

Therefore , 455/84 + 144/84 = 599/84

Now v have 2 divide d sum by their diff. . Therefore v find their diff. We shud again find their LCM = 84

So they are once again =455/84 -144/84 = 311/84

So now v divide d sum by their diff. = 599/84 / 311/84

= 599/84 * 84/311

= 599 * 1/311

= 599/311

Therefore , 599/311 is d ans .

Therefore , 455/84
