If you want to know what percent A is of B, you simple divide A by B, then take that number and move the decimal place two spaces to the right. That's your percentage! To use the calculator, enter two numbers to calculate the percentage the first is of the second by clicking Calculate Percentage.

Relative changes are shown by index numbers rather than absolute amounts of change. This is because index numbers are calculated as ratios of current values to base values, and expressed as percentages. The following points explain this concept in detail:

Definition of index numbers: Index numbers are statistical tools used to measure changes in a variable or group of variables over time. They are calculated as the ratio of current values to base values, multiplied by 100, and expressed as a percentage.

Relative changes: Index numbers show relative changes in a variable, which means that they indicate how much the variable has changed from its base value. For example, if the base value of a variable is 100 and the current value is 120, the index number would be 120/100 x 100 = 120%. This means that the variable has increased by 20% from its base value.

Absolute amounts of change: In contrast to index numbers, absolute amounts of change indicate the actual difference between two values. For example, if a variable increased from 100 to 120, the absolute amount of change would be 20.

Advantages of using index numbers: Index numbers are useful for comparing changes in variables over time, across different regions, or between different categories. They can also be used to track trends, identify patterns, and forecast future changes. Moreover, index numbers can be used to adjust for inflation, which is important for measuring real changes in economic variables.

Conclusion: In summary, index numbers show relative changes rather than absolute amounts of change. They are calculated as ratios of current values to base values, expressed as percentages, and used to compare changes in variables over time, across regions, or between categories.

The answer is A as it shows relative change rather than absolute change, though it's expressed in Percentage...
