Answer 1

6
`(1)/(4)`

Step-by-step explanation:

First you add the whole numbers 1 + 4 which will be 5

Then you add the fractions. To do that you have to make sure that the denominators are the same (in this case they are not). So you multiply the fraction by a number so the denominators can equal each other.

1 (4) /2 (4) + 3 (2) / 4 (2)

`(4)/(8)` +
`(6)/(8)` =
`(10)/(8)` = 1
`(2)/(8)` = 1
`(1)/(4)`

*always remember to simplify the fractions

After adding the fractions, you just have to add it to the whole number (5)

5 + 1
`(1)/(4)` = 6
`(1)/(4)`

hope this helps!
