Question

How do you find $0.5\% $ of $250$?

Answer 1

Hint: In order to calculate $0.5\% $of $250$, first convert percent value into decimal equivalent by dividing it with 100 and then multiply the decimal value with $250$ to get your desired result.

Complete step by step solution:
In this question we have to find $0.5\% $of $250$
Let’s interpret this into a mathematical expression. It can be
$ = 0.5\% \, \times 250$
On first we have to convert the percent value into corresponding decimal value, so to do so divide the percent value with 10 raised to the power 2.
$
   = \dfrac{{0.5}}{{100}}\, \times 250 \\
   = \dfrac{{125}}{{100}} \\
   = 1.25 \\
 $
Therefore, $0.5\% $of $250$is equal to $ = 1.25$.
Formula Used:
$p\% = \dfrac{p}{{100}}$
Here p is the percentage,

Alternative:
 If you don’t want to divide percent value by 100, we have another way to calculate decimal value i.e. by moving the decimal point 2 places in the left
For example: Calculate $0.15\% $ into decimal
Now, move the decimal point two places towards the left and remove $\% $ at the end of result.
$ = 0.0015$

Note: 1. Don’t Forgot to remove % sign when converting percent to decimal equivalent.
2. To calculate fraction from the percentage, divide the given percentage value by 100
For example: We have to write $70\% $into fraction
$
   = \dfrac{{70}}{{100}} \\
   = \dfrac{7}{{10}} \\
 $
Or
$ = 0.7$
3. If you want to Increase a Number by y %:
Example: On the off chance that a number is expanded by\[10{\text{ }}\% \], at that point it becomes 1.1 times of itself. On the off chance that a number is expanded by 30 %, at that point it becomes 1.3 times of itself.
4. If you want to Decrease a Number by y %:
Example: On the off chance that a number is diminished by 10 %, at that point it becomes 0.90 times of itself. On the off chance that a number is diminished by 30 %, at that point it becomes 0.70 times of itself.
