A hotel has 30 rooms, and each room has 6 rooms. How many people can you keep?

5x6=30 people

Option 2: Book three rooms for six and three rooms for four.

6x3+4x3

= 18+ 12

=30 (person)

Option 3: Book 1 room with 6 rooms, 6 rooms and 4 rooms.

1x6+4x6

=6+24

=30 (person)

A: You can book five 6-person rooms or three 6-person rooms and three 4-person rooms, or 1 6-person rooms and six 4-person rooms.

This topic is the choice of scheme and the calculation of multiplication and addition.

According to the meaning of the topic, the topic requires that every room should be full, that is, all the arranged rooms should be full, and no space can be left. According to the knowledge of multiplication and addition, we can get the formulas 5x6=30, 6x3+4x3=30, 1x6+4x6=30, so there are three reasonable permutation schemes.

Simple application problem solving method:

1, comprehensive method

The idea of solving problems by comprehensive method is to shift from known conditions to analytical methods of problems. The analysis method is: choose two known quantities and put forward the problems that can be solved; Then choose two known quantities and put forward the problems that can be solved; This is deduced step by step until the problem of the topic is solved.

2. Analytical method

The idea of analytical method is to start with the problem of application problems and find out the conditions needed to solve this problem according to the quantitative relationship. Some of these situations are known and some are unknown. Then, take the unknown condition as an intermediate problem, find out the conditions needed to solve this intermediate problem, and reason step by step until all the necessary conditions can be found from the topic.
