Please answer the question!

Answer 1

`30`

Explanation:

Here, we will have to use
`LCD` or, least common denominator.

The least common
`LCD` here that we will be using is going to be 30. We can always make sure by multiplying.

`(3)/(10)`*
`(3)/(3)`
`=(9)/(30)`

Our final answer for the first fraction is
`(9)/(30)` which could be simplified back to
`(3)/(10)`.

For the second fraction, we will be multiplying with
`(2)/(2)`.

`(2)/(15)`*
`(2)/(2)`
`=(4)/(30)`.

Again, it simplifies back to
`(2)/(15)`.

Hence, the
`LCD` is
`30`.

Hope that helps:D
