Percents | |
Math Example: Percents with Double Number Lines: Example 1 | Math Example: Percents with Double Number Lines: Example 1TopicRatios, Proportions, Percents DescriptionThis example demonstrates how to find 50% of 250 using a double number line. The solution shows two parallel number lines: one ranging from 0 to 100% and the other from 0 to 250. By aligning 50% on the percentage line with its corresponding value on the numerical line, we can see that 50% of 250 is 125. This method visually represents the concept that 50% is equivalent to one-half of a quantity. |

Math Example: Percents with Double Number Lines: Example 14 | Math Example: Percents with Double Number Lines: Example 14TopicRatios, Proportions, Percents DescriptionThis example illustrates how to calculate what percent one number is of another using a double number line. The image depicts two parallel number lines: one spanning from 0 to 100% and another from 0 to 396, with 198 marked at the midpoint. This visual representation helps students understand the relationship between the part (198) and the whole (396) in percentage terms. |
Ratios and Rates | |
Math Example: Percents with Double Number Lines: Example 15 | Math Example: Percents with Double Number Lines: Example 15TopicRatios, Proportions, Percents DescriptionThis example demonstrates how to determine what percent one number is of another using a double number line, particularly when dealing with more complex ratios. The image shows two parallel number lines: one ranging from 0 to 100% and another from 0 to 856, with 107 marked at an eighth of the way. This visual representation helps students understand the relationship between the part (107) and the whole (856) in percentage terms. |
Ratios and Rates | |
Math Example: Percents with Double Number Lines: Example 2 | Math Example: Percents with Double Number Lines: Example 2TopicRatios, Proportions, Percents DescriptionThis example illustrates how to calculate 25% of 180 using a double number line. The solution presents two parallel number lines: one spanning from 0 to 100% and the other from 0 to 180. By aligning 25% on the percentage line with its corresponding value on the numerical line, we can determine that 25% of 180 is 45. This method visually demonstrates that 25% is equivalent to one-quarter of a quantity. |
Ratios and Rates | |
Math Example: Percents with Double Number Lines: Example 3 | Math Example: Percents with Double Number Lines: Example 3TopicRatios, Proportions, Percents DescriptionThis example demonstrates how to find 33 1/3% of 240 using a double number line. The solution displays two parallel number lines: one ranging from 0 to 100% and the other from 0 to 240. By aligning 33 1/3% on the percentage line with its corresponding value on the numerical line, we can see that 33 1/3% of 240 is 80. This method visually represents the concept that 33 1/3% is equivalent to one-third of a quantity. |
Ratios and Rates | |
Math Example: Percents with Double Number Lines: Example 4 | Math Example: Percents with Double Number Lines: Example 4TopicRatios, Proportions, Percents DescriptionThis example illustrates how to calculate 40% of 105 using a double number line. The solution presents two parallel number lines: one spanning from 0 to 100% and the other from 0 to 105. By aligning 40% on the percentage line with its corresponding value on the numerical line, we can determine that 40% of 105 is 42. This method visually demonstrates that 40% is equivalent to two-fifths of a quantity. |
Ratios and Rates | |
Math Example: Percents with Double Number Lines: Example 5 | Math Example: Percents with Double Number Lines: Example 5TopicRatios, Proportions, Percents DescriptionThis example demonstrates how to find 12.5% of 88 using a double number line. The solution shows two parallel number lines: one ranging from 0 to 100% and the other from 0 to 88. By aligning 12.5% on the percentage line with its corresponding value on the numerical line, we can see that 12.5% of 88 is 11. This method visually represents the concept that 12.5% is equivalent to one-eighth of a quantity. |
Ratios and Rates | |
