The total donation of the whole school is 2400 yuan. How much money does class 6 (1) donate? Use two methods to calculate?

1. Step by step, calculate the donation amount of grade 6 2400x1 / 4 = 600 yuan, and the donation amount of class 1 of grade 6 = 600 yuan / 3 = 200 yuan
2. As a whole, the proportion of the first class of grade six in the whole school is 1 / 3x1 / 4 = 1 / 12, and the number of students in the whole school is 2400x1 / 12 = 200 yuan

Contribution of 1 class: 2 / (3 + 2) = 2 / 5
Contribution of 2 classes: 3 / (5 + 3) = 3 / 8
So the contribution of three classes accounts for 1-2 / 5-3 / 8 = 9 / 40
The total amount of donation is: 1800 × (9 / 40) = 8000 yuan
A: Class Three donated 8000 yuan
