There are a couple of simple steps we need to follow to find out the percentage change between 2 to 48. First of all, we need to deduct the number we want to measure the change from, 2 from the number we want to measure the change to, 48:
Now that we have the number 46, we can work out the decimal change by dividing it by the number we want to measure the change from, 2:
The final step in working out the change from 2 to 48 is to multiply our decimal number by 100. Remember that "percent" means parts per hundred, and this is why we have to multiply it by 100 to get our answer:
(Note that we have rounded the final percentage down to two decimal places)
As you can see, the actual process of calculating the percentage change from 2 to 48 is relatively straightforward to do. We can now easily see that the percentage change from 2 to 48 is an increase of 2300%.
Why Calculate a Percentage Change?
Percentages are very useful to make calculations easier and to understand numbers and the differences between them. It's much simpler to work with and understand parts of 100 than it is to use fractions that often do not have an exact, non-recurring, decimal equivalent.
Since a percentage is really just a fraction where the denominator is 100, comparisons are easier too.
For a percentage change, like from 2 to 48, we do these types of calculation all the time in real life. A few examples might be:
- A business might want to calculate whether their profit margin is increasing or decreasing
- An employee who worked extra hours this month might be curious to find out how much extra work he did as a percentage
- An investor looking at their portfolio might want to work out whether their investments have increased or decreased
