Answer 7

Remember, you can do whatever operation you want to the equation, you have to just do it on both sides of the equality

Answer 8

\[\frac{ 5 }{ 1 }*\frac{ -2 }{ 5 } = \frac{ -10 }{ 5 } = -2\]

Answer 9

When you multiply, this happens
\[\frac{ a }{ b }*\frac{ c }{ d } = \frac{ a*c }{ b*d }\]
