Question

Solve four-tenths plus four ninths

Answer 1

`(38)/(45)`

Explanation:

`(4)/(10) +(4)/(9)`

So first you need to have a common denominator (the number on the bottom)

The least common denominator (LCD) would be 90.

So then the fractions would be:
`(36)/(90) +(40)/(90)`.

Add.

You get:
`(76)/(90)`

Simplify and the answer is
`(38)/(45)`
