Question

How do you multiply `3 times 3/5`?

Answer 1

`9/5`

Explanation:

`color(blue)("One way of looking at it")`

This is 3 lots of `3/5` so we have `3/5+3/5+3/5`

As all the bottom numbers (denominators) `ul("are the same")` we can DIRECTLY add the top numbers (numerators) .

`(3+3+3)/5 =9/5`
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
`color(blue)("Another way of looking at it")`

Did you know that you can write for example: `1,2,3,4` and so on as `1/1,2/1,3/1,4/1` and so on.

This is 3 lots of `3/5` so we have `3/1xx3/5 = (3xx3)/(1xx5)=9/5`
