The formula

Because it can be divided by 6, the maximum remainder is 5, and the maximum remainder by 7 is 6, so first calculate 6 * 7 = 42, 42-1 = 41, which is at least the number of basketball to buy

In science class, Mr. Li made an experiment for his classmates: there are two cups a and B. A has 1000 grams of water, and B is empty. For the first time, Mr. Li gave 1 / 2 of cup a to B, B gave 1 / 3 to a, gave 1 / 4 of cup a to B for the third time, and poured 1 / 5 of cup b back to a for the fourth time After pouring for 2011 times, what will happen to the water in cup a and cup B? Is there more water in cup a or cup B? Please explain why

Cup a is as much as cup B, because 2011 is the base, that is to say, when we turn back to the first time, when cup a is 500g and cup B is 500g
Remember to adopt it
