(Giving brainliest) Solve five ninths plus four sixths.

A) sixty six fifty fourths
B) ten fifteenths
C) thirty ninths

Make it the same denominator so you can add them (18.)
Multiply 5/9 by 2 and multiply 4/6 by 3.
10/18 + 12/18 = 22/18.
Since there is not 22/18 listed, you can use this fraction as a proportion. The only proportion that can be evident is answer A, as when you multiply 22/18 by 3, you get 66/54.
Your answer is A.
