Answer:
A. 1 11/20
Step-by-step explanation:
There are two ways to solve this problem.
First, we can find their LCD and adjust their numerators to find the sum.
3/4 + 4/5 = 15/20 + 16/20 = 31/20 = 1 11/20
Another option is to add the two fractions as decimals.
3/4 + 4/5 = 0.75 + 0.8 = 1.55 = 1 11/20
Either way, we get the same answer which is 1 11/20. The correct answer is Option A.
Hope this helps!
