What is 7 over 12 / 5 over 9? answer truthfully, !

In math, "over" and "/" and "÷" mean the same thing. The expression you have written is

... 7/12/5/9 = 7/540

It seems possible you may want the ratio of two fractions to be simplified. Perhaps you intend ...

... (7/12)/(5/9) = (7/12)×(9/5) = (7×9)/(12×5) = 63/60

... = 21/20 = 1 1/20

Dividing by anything is the same as multiplying by its reciprocal. This is a convenient fact when dividing by a fraction.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
