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
