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.
