Question

How do you add `3 4/5 + 1 2/3`?

Answer 1

We first find the smallest number that is divisable by 5 and 3.

Explanation:

It's easy to see that this is `15`.
Now we can multiply the `4/5` part by multiplying by `1=3/3`:
`4/5xx3/3=12/15`

Same goes for:
`2/3xx5/5=10/15`

Putting it all together we have:
`3 12/15+1 10/15=4 22/15`

We can take out `15/15=1` to get `5 7/15`
