The average score of Chinese and Mathematical Sciences in Ping Li is 80, and the score ratio of the three subjects is 8:75. How many points did he get respectively?

There are two ways to make this formula:

First calculate the total score of three subjects, 80×3=240 (points).

240/(8+7+5)= 12 (point)

The language is 12×8=96 (minutes).

Mathematics 12×7=84 (points)

Science 12×5=60 (points)

So the language is 96 points; Mathematics 84 points; 60 points in science? .

2. Calculate the total score of three subjects first, 80×3=240.

The language is 240×8/(8+7+5)=96.

Mathematics 240×7/(8+7+5)=84

Science 240×5/(8+7+5)=60
