The answer is C because if you replace the variables with 0 and 3, it makes the equation reasonable.
well half 40 is 20 and 1 third of 60 is 20 and 1 fourth of 80 is 20 and i 1 fifth of 100 is 20 so that is who they are related
It would be 4
so x=4
because 18 and 6 are the bases and 6 goes into 18 3 times. so what goes into 12 3 times, 4.
