Answer:
30
Explanation:
1) Convert everything on both sides to a common denominator, I will use 50
1 1/10 = 11/10 = 55/50
3 3/5 = 18/5 = 180/50
3 = 150/50
1 = 50/50
?/50 = ?/50
5/50 = 5/50
2) Re-plug everything in and simplify
55/50 + 180/50 = 150/50 + 50/50 + ?/50 + 5/50
235/50 = 205/50 + ?/50
3) How many 1/50 will it take to get 205/50 to 235/50?
235-205 = 30. Therefore 30/50 but since the ? is only for the numerator
Final Answer = 30
