Answer: 41/42
Explanation:
1. You are given the mixed numbers 4 35/42 and 3 36/42. Multiply the whole number by the denominator and add it to the numerator. In this case, do 4*42, which gives us 168, which when added to 35, gives us 203/45. Doing this for 3 36/42 gives us 162/45, by multiplying 3 by 42, and then adding 36 to the result.
2. Subtract 203 - 162, which is 41. With a denominator of 42, this gives us 41/42.
