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!
