A)4÷(-2)
b)4×(-2)
c)(-10)÷1×(15)
d) -4÷10

Step-by-step explanation:

a)4÷(-2) = (-2)

b)4*(-2) = (-8)

c)(-10)÷1*(15) = (-10)*15=(-150)     {first division, then only multiplication}

d)(-4)÷10= -0.4

Good evening

Step-by-step explanation:

a)4÷(-2) = [(-2)(-2)]/(-2) = -2

b)4×(-2) = -(4×2) = -8

c)(-10)÷1×(15) = (-10)/(15) = -(5×2)/(5×3) = -(2)/(3) = -2/3

d) -4÷10 = -(2×2)/(2×5) = -2/5.
