I need to know how to get the answers I’m new to this

Answer 1

Always that we have an integer, let's say 2, we can rewrite it like:

`(2)/(1)`

This will help us when multiplying fractions. To multiply two fractions, we simply multiply the numerator with the numerator and denominator with denominator. In this case:

`\begin{gathered} 2*-(7)/(4)=(2)/(1)*-(7)/(4)^{} \\ \\ -\frac{2*^{}7}{1*4} \end{gathered}`

And then solve:

`-\frac{2*^{}7}{1*4}=-(14)/(4)`

Now we can further simplify this fraction, because 14 and 4 are divisible by 2, then:

14 = 2 x 7

4 = 2 x 2

Then the final answer is:

`-(7)/(2)`
