Description

"Application of Percents (3)" PPT

Part One: Learning Objectives

1. Guide students to further understand the application of percentages in life, deepen their understanding of the connotation of percentages, and master the problem-solving ideas for solving percentage application problems by formulating equations.

2. Improve the ability to use mathematics to solve practical problems and further understand the close connection between percentages and real life.

3. Broaden students' knowledge through understanding of "Engel's coefficient".

Learning focus: Solve practical problems by formulating equations based on the meaning of percentages.

Learning difficulty: How to find the equivalent relationship based on the meaning of the question.

Learning methods: Review the questions carefully, find out the equivalent relationship based on the meaning of the questions, and list the equations correctly.

Percent Application PPT, Part 2: Interactive New Teaching

Based on these equivalence relations, what method can we use to solve it?

Can make equations to solve problems.

Let’s talk about the basic steps of formulating equations.

1. Find; 2. Assume; 3. List; 4. Solve; 5. Test.

Solution: Suppose the total household expenditure of the Xiaoxiao family in 2000 is x yuan, then the food expenditure is 55% x yuan, and other expenditures are 45% x yuan.

55%x- 45%x=620

10%x=620

x=6200

Answer: Xiaoxiao’s family’s total household expenditure is 6,200 yuan.

Application of percentages PPT, part 3: Class summary

x represents the standard amount, A% and B% respectively represent the percentage of the two partial amounts corresponding to the total amount.

Method 1: A%x±B%x=sum (or difference) of the two parts

Method 2: (A%±B%)x=sum (or difference) of the two parts
