Answer 1

Hii.. frnd... I'm here to help you...

Sum of 5/21 and 4/7 ---
--> 5/21 + 4/7
--> LCM is 21
--> 5+12/21
--> 17/21

Difference of 5/21 and 4/7 -----
--> 5/21 - 4/7
--> LCM is 21
--> 5-12/21
--> -7/21
--> -1/3

now we have to divide 17/21 to -1/3
--> 17/21 * -3/1
--> -17/7

So.. the final answer is -17/7.

Hope this helps you...
all the best...
