the sum of three numbers is 54 the first number is twice the size of the 2nd and one third of the third number what are the numbers adding to 54

Answer 1

Let x=2nd number

Then 2x=1st number

And 6x=3rd number, since this must be triple the 1st number.

Then, x+2x+6x=54, or 9x=54.

So, x=6(2nd number), 2x=12(1st number), and 6x=36(3rd number).
