Question

One number is one third of another number. The sum of both numbers is 16. Find the numbers.

Answer 1

12 and 4

Explanation:

we can solve this through a system of equations.

one number is a third of the other

1/3x = y

added together they equal sixteen

x + y = 16

substitute in for y

1/3x + x = 16

x = 12

put this in the original equation and

y = 4

Answer 2

Answer: 4 and 12

Explanation:

Let x be the "another number"

Therefore, "one number" is 1/3x

1/3 x + x = 4/3 x

4/3 x = 16

1/3 x = 4

x = 12

Therefore, the numbers are 4 and 12.
