12(2)/(7)

Explanation:

we have


1(3)/(7) +10(6)/(7)

step 1

Convert mixed number to an improper fraction


1(3)/(7)=(1*7+3)/(7)=(10)/(7)


10(6)/(7)=(10*7+6)/(7)=(76)/(7)

step 2

Substitute in the expression above and find the sum


(10)/(7)+(76)/(7)=(86)/(7)

Convert to mixed number


(86)/(7)=(84)/(7)+(2)/(7)=12(2)/(7)
