The number ratio of the first team to the second team is 3:2, the number ratio of the second team to the third team is 5:4, what is the number ratio of the first team to the third team What's the formula
Suppose there are 15 people in the first team, 10 people in the second team and 8 people in the third team
So the number ratio of the first team to the third team is 15:8
There are two transport teams. The first team has 32 people and the second team has 28 people. Due to the need of the task, it is necessary to transfer more people from the second team to make the number of the first team twice that of the second team
Less support for the first team?
Set up x people
32+x=2*（28-x）
The solution is x = 8
