Answer:
180/7
Step-by-step explanation:
Take LCM of denominators which are 7 and 1 in this case
LCM of 7 and 1 is : 7
So multiply each denominator with a number which will turn them into 7
( You have to do the same with numerator )
110 × 1 / 7 × 1 + 10 × 7 / 1 × 7
110/7 + 70/7
(when denominators or numbers at the bottom are same, you can add them directly)
(110+70)/7
180/7 is the answer
