Question 517508
Let a = "one number
Let b = "another number
:
Write an equation for each statement:
:
"One number is 25% of another.
a = .25b, (obviously, a is the smaller number)
:
"The larger number is 12 more than the smaller number. 
b = a + 12
:
(FRom the 1st statement,)  replace a with .25b, in the above equation
b = .25b + 12
b - .25b = 12
.75b = 12
b = 12/.75
b = 16
then
a = .25(16)
a = 4
:
Check this in the 2nd statement
