Question 723804: the ratio of two numberds is 3:4. If the difference is 12 find its smaller number

Call the numbers x and y

x/y = 3/4 and y-x = 12 so y=x+12

Substitute that y value (x+12) into the proportion and then solve for x.

x/(x+12) = 3/4 ---> 4x = 3(x+12) = 3x + 36

x=36

y-36 = 12 ---> y = 48
