Answer 1

Explanation:

The question is not properly structured but we can as well find the sum of 5/7 and 10 as shown;

`(5)/(7)+ (10)/(1) \\The \ LCM \ is \ 7\\\\= (5(1)+10(7))/(7)\\\\= (5+70)/(7)\\\\= (75)/(7) \\\\= 10 (5)/(7)`

Hence the expression written in equivalent form of common denominator is
`(5 + 70)/(7)`

The sum is
`10 (5)/(7)`
