Answer:
3 1/5 = 16/5
4/16 = 1/4
simply and find a common denominator, in this case it is 20. Multiply the top and bottom by the same number, to get the bottom to twenty. So, to get 5 to 20, you must multiply by 4, so you have to multiply the top by 4 too, which is 64. Do the same for the next fraction.
16/5 = 64/ 20 (both x4)
1/4 = 5/20 (both x5)
now add
64/20 + 5/20 = 69/20
69/20 is the final answer because it cannot be simplified futher.
