Description
"Basic Properties of Proportion" Proportion PPT Courseware 4
1. What is proportion?
An expression that expresses the equality of two ratios is called a proportion.
2. What are the differences and connections between ratio and proportion?
The four numbers that make up a proportion are called the terms of the proportion. The two terms at the two ends are called the external terms of the ratio, and the two terms in the middle are called the internal terms of the ratio.
3×40 = 20×6
Based on the above equation, can you determine which two are external terms? Which two are internal terms?
According to the basic properties of proportion, we know that the product of two internal terms is equal to the product of two external terms. Understanding it backwards, two multiplication expressions whose products are equal (and not 0) can also be rewritten as proportions.
