Two fifths of Li Gang's height is exposed above the counter, and three fifths remain under the stage.

1 of Wang Yi's height is exposed above the counter, and 1 is left under the stage.

65,438+0 of joy chen's height is exposed above the counter, and the remaining 2/3 is under the stage.

Three fifths of Li Gang's height is equal to two thirds of Wang Yi's height, and 1 is equal to two thirds of joy chen's height.

Their height ratio is

3/5, 1: 2/3,

That is 18: 15:20.

Then it's just a matter of proportional distribution. Stop teaching, right?
