Answer 2

29

Explanation:

I'm going to write both of this as improper fractions.

That is the mixed fraction
`a(b)/(c)` can be written as the improper equivalent fraction of
`(ca+b)/(c)` assuming
`a` is positive.

So we are going to write
`-3(1)/(3)` as
`-(3(3)+1)/(3)`.

Simplifying that gives us
`-(10)/(3)`.

Now for
`-8(7)/(10)=-(10(8)+7)/(10)=-\fraC{87}{10}`.

Now we are ready to find the product which just means multiply:

`(-10)/(3) \cdot (-87)/(10)`

To multiply fractions you just multiply straight across on top and straight across on bottom unless you see a common factor on and bottom to cancel (and I do; I see 10)

`(-1)/(3) \cdot (-87)/(1)`

`(87)/(3)`

Negative times negative is positive.

Anyways time to write 87/3 as a mixed fraction.

How many 3's are in 87? 29 with no remainder
