The second floor (snowball 70 12 1), the correct answer should be 600. By the way, explain the mistakes about 6 and 8 on the first and fourth floors. According to the algorithm on the first floor, 1 to 48 should be INT[48/(6*8)]= 1, but there is actually 20. And all the natural numbers in 500 that are divisible by 3 and 4? Is equal to, and 3,4 have no common factor, so we can consider using the formula INT[500/(3*4)]=4 1. At the same time, there is no common factor between 5 and 6,8, so INT[4 1/5]=8 can be used.

If you don't understand? Set the algorithm, see the following figure:?

Theory of Three Represents Theory 1000 Middle School? what's up A circle of elements divisible by 5, 6 and 8, if you directly add three circles and a slash? how much is it? Once, the double slash was added twice, so we have to subtract three long ones like Type A, and then the double slash was subtracted again, so we have to add three long ones like Type B, that is, all three have * * *.
