From the fill-in-the-blank of (1), we can know that Team B plans to complete 3/5 of all tasks; Actually completed 5/9 of all tasks. When Team A completes the planned tasks (2/5 of all tasks), Team B completes all tasks (2/5)*(5/4)= 1/2.

So the equation (5/9)x-( 1/2)x=200.

10x-9x=3600 denominator, and both sides are multiplied by 45 at the same time.

X=3600 (m) Merge similar items.
