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.

What is the value of y2 – x2 when y = 6 and x = 5?
Papessa [141]

Answer:

y^2 - x^2 = 11

Step-by-step explanation:

5 x 5 = 25

36 - 25 = 11
