Question

What is four fifths plus eight ninths

Answer 1

4/5 + 8/9. First we have to find a common denominator for
`(4)/(5)` and
`(8)/(9)`.
`\\ (4*9)/(5*9)= (36)/(45) \ and \ (8*5)/(9*5)= (40)/(45) \\` Now we are going to add:
`(36)/(45)+ (40)/(45)= (76)/(45)` Make
`(76)/(45)` a mixed number:
`(76)/(45)=1 (31)/(45)` So the answer is
`\boxed{1 (31)/(45)}`
