Team a and team B built a road. Team a built two fifths of the road, team B built the remaining two thirds, and team B built several parts of the road Make it up later What percentage of the road has team B built? right off! It's urgent!

(1-2/5)*(2/3)=(3/5)*(2/3)=2/5
2/5



The sum of a and B is 250. The number of a is one ninth less than that of B. what are the two numbers


Let a be X
x(1-1/9)-(250-x)=5;
8x/9-250+x=5;
17x/9=255;
x=135;
A is 135, B is 115



There are 272 workers in engineering team a and 196 workers in engineering team B. according to the requirements of work, the number of workers in team B is 13 times that of team a and should be transferred from team B______ I'm going to team a


Suppose we should transfer x people from team B to team a, 196-x = 13 (272 + x), the solution is x = 79, so the answer is: 79
