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?
