Answer:

1. 10 6/7      2. 8/15

Step-by-step explanation:

1. 6 1/42 + 4 5/6

  • First, let's combine the whole numbers.  6 + 4 = 10
  • Now we are left with 1/42 + 5/6.
  • To add or subtract, the dominators need to be the same. We need to find the least common multiple which here is 42.

1/42 + 5/6(7)

1/42 + 35/42

= 36/42

= 6/7

  • All we have to do is combine both numbers.

10 6/7

2. 13/15 - 1/3(5)

13/15 - 5/15

8/15
