One number is 2/3 of another number. The sum of the two numbers is 20. Find the two numbers. Use a comma to separate your answers.
.
Let x = one of the numbers
then from "One number is 2/3 of another number." we have
(2/3)x = second number
.
x + (2/3)x = 20
multiply both sides by 3:
3x + 2x = 60
5x = 60
x = 12
.
second number:
(2/3)x = (2/3)12 = (2)4 = 8
.
answer: 8,12
