Transcript text: Why is each section of the percent bar equal to 3 ?

Solution

Solution Steps

Step 1: Analyze the top number line

The top number line represents percentages from 0 to 100. Each section represents 10%.

Step 2: Analyze the bottom number line

The bottom number line is divided into sections. Each section corresponds to a 10% section on the top number line. The numbers on the bottom number line increase by 3 for each section.

Step 3: Find the relationship between the two number lines

Since each 10% section on the top corresponds to a section of 3 on the bottom, then each 10% is equivalent to 3 units on the bottom number line. We can think of the bottom number line as a different scale representing the same quantity as the top number line.

Final Answer

Each section of the percent bar is equal to 3 because each 10% on the top number line corresponds to 3 units on the bottom number line. Essentially, the bottom number line uses a different scale.
