It takes 6.1 seconds for Xiaoying to calculate a problem, and it takes 2 and 2 / 3 seconds for Xiaojun to calculate a problem. Who can calculate fast?

It takes 6.1 seconds for Xiaoying to calculate a problem, and it takes 2 and 2 / 3 seconds for Xiaojun to calculate a problem. Who can calculate fast?

2 and 2 / 3 = 8 / 3 seconds
6.1>8/3
So the time of small army is short, so the calculation of small army is fast
