Step-by-step explanation: first we need the values in the numerator, so we can multiply in X where you multiply the denominators with numerator of the other value in the equation finally we resolve simple equation between both numerator, so the numerator equations will be.
(-10) * (-3) = 30
(-8) * ( -1) = 8
then we get this values in the numerator
30 + 8 = 38
in the denominator we only need to multiply both values.
(-8) * (-10) = 80
after we divide each result between 2
numerator 38/2 = 19
denominator 80/2 = 40
after this, we can place the numerator and the denominator into the equation and we get the following result
