So we need to break 846 in 3 parts (I assume those parts ADD to 846).
Let's call part 1 "x"
Call part 2 "y"
and part 3 "z".
Well, the idea was that x + y + z = 846.
It also says that: "the second part is twice the third part." So y = 2x
Finally, it says that: "the third part is triple the second part." So z = 3y
Now let's go back to our original equation x + y + z = 846.
Let's plug in values for y and z: x + 2x + 3y = 846 ---> x + 2x + 3(2x) = 846
---> x+ 2x + 6x = 846.
Now just solve for x, and plug it back in to find y and z.
I hope this helps!!
Best,
