Answer:

1. 6 13/15

2. 14/60 or 7/30

3. 1 11/20

4. 3 1/42

Step-by-step explanation:

take the LCM of the denominators (like 2/3 and 6 1/5 would be 15) and multiply both the numerator and denominator by whatever number makes the denominator the LCM. (so 2*5/ 3*5 would get 10/15 and 1*3 and 5*3 would get 3/15, add to get 6 13/15 the 6 is the whole number that 1/5 came attached to which can get bigger or smaller if you had for example 16/15 would be 7 1/15)
