Answer 2

Hello!

The answer are:

• 
  `(-8)/(15)`
• 
  `-1`
• 
  `-2`
• 
  `(-3)/(10)`

Why?

Fraction multiplications are lineal, it means that when we want to multiply a fraction by other fraction, we should multiply numerators by numerators and denominators by denominators.

Calculations:

`(2)/(3)*(-4)/(5)=(-8)/(15)\\\\(-5)/(7)*(7)/(5)=(-35)/(35)=-1\\\\ (-2)/(39)*39=(-78)/(39)=-2\\\\(2)/(5)*(-3)/(4)=(-6)/(20)=(-3)/(10)`

Have a nice day!
