x + y = 5/4
x = .5*y
this makes:
y = 2*x
substituting in original equation gets:
x + 2*x = 5/4
combine like terms to get:
3*x = 5/4
divide both sides by 3 to get:
x = 5/12
y = 2x so:
y = 5/6
substitute in original equation of x + y = 5/12 to get:
5/12 + 5/6 = 5/12 + 10/12 = 15/12 = 5/4
since x = 5/12 and y = 5/6, the product of the two numbers is:
5/12 * 5/6 = 25/72
that would be selection A.
