I am sorry I cannot solve this problem.
However, I have a tip: if you are gonna give
problems as hard as these, you might wanna offer more than just 5 points. Or you can just waste your points and get a zillion non-helpful answers like this one.

Answer:
41/20
Step-by-step explanation:
Simplify the following:
4/5 + 1/2 + 3/4
Hint: | Put the fractions in 4/5 + 1/2 + 3/4 over a common denominator.
Put 4/5 + 1/2 + 3/4 over the common denominator 20. 4/5 + 1/2 + 3/4 = (4×4)/20 + 10/20 + (5×3)/20:
(4×4)/20 + 10/20 + (5×3)/20
Hint: | Multiply 4 and 4 together.
4×4 = 16:
16/20 + 10/20 + (5×3)/20
Hint: | Multiply 5 and 3 together.
5×3 = 15:
16/20 + 10/20 + 15/20
Hint: | Add the fractions over a common denominator to a single fraction.
16/20 + 10/20 + 15/20 = (16 + 10 + 15)/20:
(16 + 10 + 15)/20
Hint: | Evaluate 16 + 10 + 15 using long addition.
