12 1/5 - 5 6/7

Question

i am not sure how to solve this

Answer 1

12 1/5 = 61/5

5 6/7 = 41/7

Now give them a common denominator 35, then add the numerators

427/35 + 205/35 = 632/35 = 18 2/35

or just add the integers first

12+5 = 17

then add the fractions

1/5 + 6/7

7/35 + 30/35 = 37/35 = 1 and 2/35

17+ 1 2/35 = 18 2/35

add 17 and 1 2/35 to get 18 2/35
