Question

What number is \[18\% \] of $ 250 $ ?

Answer 1

Hint: To simplify this question , we need to solve it step by step . In order to determine what number is \[18\% \] of $ 250 $ . We need to first convert the percent into its number form to get rid of the percent sign and then divide it by 100 as the percent itself means divide the decimal by 100 . Also we will perform some calculations to simplify the given equation . Before that we need to determine the mathematical expression from the above statement , first we have to understand the statement carefully .

Complete step by step solution:
We need to formulate the mathematical statement into the mathematical equation and you will be able to do this only when you are having a good understanding of the concept .
Now , the question says what number is \[18\% \] of $ 250 $ .
We are given with the percentage \[18\% \] and need to convert this into the fraction form .
Now , we need to just divide the percentage by 100 so that we can get rid of the percentage sign and can convert into the form of fraction so that calculation becomes easy .
By performing this calculation we will be getting –
 $ 18\% = \dfrac{{18}}{{100}} $
The term ‘OF’ in the question means multiplication , so replace ‘of’ with multiplication we would get it as –
\[18\% \] of $ 250 $
 $ \dfrac{{18}}{{100}} \times 250 $
Cancel out the common factors to simplify the calculation .
 $
  \dfrac{9}{{50}} \times 250 \\
  9 \times 5 \\
  45 \;
  $
Therefore , the required number is 45 .
So, the correct answer is “45”.
