Hello!
The answer to your problem is 7 1/24
Turn 2 7/8 into an Improper Fraction
Multiply 2*8 and get 16. Now add 7 and get 23 (Denominator stays the same)
2 7/8 = 23/8
Turn 4 1/6 into an Improper Fraction
Multiply 4*6 and get 24. Now add 1 and get 25 (Denominator stays the same)
4 1/6 = 25/6
Add
23/8 + 25/6 = 169/24
Turn 169/24 into a Mixed Number (Divide)
169/24 = 7 1/24
Hope This Helps!
