Ответ:
141 1/4
Step-by-step explanation:
You are looking for TOTAL change, thus, both values will be positive. In order to add both fractions, you need to convert the denominator for 90 1/2 into a 4. This becomes 90 2/4.
Now add both mixed fractions.
3/4 + 2/4 = 1 1/4
90 + 50 = 140
140 + 1 1/4 = 141 1/4
