Question

How do you write 0.72 in a percentage?

Answer 1

Hint: To convert it into a percentage, we need to multiply with $ 100 $ to get a solution. It’s common for every problem. It is easy to convert a fraction into percentage, but in the case of decimal value, we need first convert it into percentage form and then we have to convert it into percentage.

Complete step by step solution:
Considering the given problem,
 $ 0.72 $
We know that percent means per hundred, we are going to get the given number in that form, we should multiply and divide 100 in the numerator and denominator. So, we get
 $ 0.72 \times \dfrac{{100}}{{100}} $
Then we are going to get in the form such that it is in the required form for percentage. Then we get
$\Rightarrow \dfrac{{72}}{{100}} $
Which means $ 72\% $
This is the required solution.
So, the correct answer is “ $ 72\% $ ”.

Note: Let consider a problem, convert $ 0.727 $ in to percentage and now change this into fraction, we get $ \dfrac{{727}}{{1000}} $ , to convert it into percentage we have to multiply it with $ 100 $ we get $ 72.7\% $ . This is our required answer. This is just another model which seems to be confusing and there are three different models in this topic. If you find time, go through all those problems.
Since, the given number is not large in decimal. Therefore, it was easy but, in some cases, the decimal value can be big, so we have to be careful while shifting the decimal points as even a single mistake can bring a lot of difference in the resultant solution.
