Answer 1

Answer:

make me as branlist

Step-by-step explanation:

If 1/x : 1/y : 1/z = 2 : 3 : 5 then what is x : y: z?

Others have given one possible solution, but it’s not the only one.

x:y:z :: (1/2):(1/3):(1/5) :: (30/2):(30/3):(30/5) :: 15:10:6 :: 30:20:12 :: 45:30:18

You can multiply each term by any constant. The simplest whole number form is x = 15, y = 10, z = 6 but other possibilities above are equally valid (including 1/2, 1/3, 1/5 or 7/6, 7/9, 7/15 etc.).
