The answer is 43 when you add 29 back to 57 then divide by 2
Multiply the first fraction by two and the second by twenty five on both top and bottom.
16/50 + 25/50 = 41/50
Infinitely many solutions is the correct answer
The answer would be 43 because when you have a number that is over 5 to the right of the number you want to round, in this case it is the 2, you round up. so because there is a 6, it is above 5, the 2 would go up to a 3.
