Arbor Day is coming. The fourth grade students planted 36 trees, and the fifth grade students planted 65438+, which is 0.5 times that of the fourth grade. How many trees are worth in the fifth grade? Writing horizontal style has the idea of solving problems. The fourth-grade students planted 36 trees, and the fifth-grade students planted 65438+, which is 0.5 times that of the fourth grade.

This means that there are as many fifth-grade students as fourth-grade students, and half of them are redundant.

He is 1.5 times, then the fourth level is multiplied by 1.5 times to get the fifth level.

36× 1.5 = 54.
