First thing to do is to pick the option one after the other and start multiplying it with eachother
A) -20
B) -10
C) 2^-4
D) 3^-2
Possible Multiplication
A*B= -20 * -10 = 200
A*C= -20 * 1/16= -20/16= -1.25
A*D= -20 * 1/9= -2.22
B*C= -10* 1/16 = -0.625
B*D= -10 * 1/9= -1.111
C*D= 1/16 * 1/9= 1/144= 0.0069
Using a number Line, th only option between the answers is -0.625 which is the product of B (-10) and C (2^-4)
Answer: B and C
