Explain how to make a bar diagram to find 30% of 450, then find the answer. Include the number of segments and the values that would go in each. Draw a bar and divide it into 10 equal segments, as the percentage is based on 100. Since you are finding 30%, you need 3 segments to represent this percentage. Divide 450 by 10 to find the value of each segment: 450 ÷ 10 = 45. Each segment represents 10% of 450, so each segment has a value of 45. To find 30%, add the value of 3 segments: 45 + 45 + 45 = 135. Therefore, 30% of 450 is 135.

Step 1:
I'll solve this problem following the LaTeX formatting guidelines precisely:

Step 2:
: Understand the Bar Diagram Concept

- Each segment represents $$\frac{1}{10}$$ or 10% of the total value
- We will create a bar divided into 10 equal segments

Step 3:
: Calculate the Value of Each Segment

- Value per segment: $$\frac{450}{10} = 45
- Total value: 450 - Number of segments: 10

Step 4:
: Identify the Segments for 30%

\boxed{\square\square\square\square\square\square\square\square\square\square}
- 30% corresponds to 3 out of 10 segments - Visual representation: (3 segments shaded to represent 30%)

Step 5:
: Calculate 30% of 450

- Value of 3 segments: $$45 \times 3 = 135

Final Answer

30\% \text{ of } 450 = 135
