Question

What’s 1 2/6 + 3 4/8. Help

Answer 1

`4 (5)/(6)`

Explanation:

We can write
`1 (2)/(6)` as
`(8)/(6)` and we can write
`3 (4)/(8)` as
`(28)/(8)`. So the question becomes
`(8)/(6) + (28)/(8)`. We can simplify both fractions so that the expression is
`(4)/(3) + (7)/(2)` and to add the two fractions we need to find a common denominator. The least common multiple of 2 and 3 is 6, so we want the denominator to be 6 in both fractions. To do this, we multiply
`(4)/(3)` by
`(2)/(2)` and we multiply
`(7)/(2)` by
`(3)/(3)`.

So finally we get
`(4)/(3) * (2)/(2) + (7)/(2) * (3)/(3)`, which is
`(8)/(6) + (21)/(6)`, which is
`(29)/(6)`.

And now all we have to do is rewrite the improper fraction
`(29)/(6)`. Notice 6 goes into 29 exactly 4 times, with a remainder of 5. So the expression simplifies to
`4 (5)/(6)`
