Question

What is $0.1$ as a percent?

Answer 1

Hint: From the question we have been asked to find the $0.1$ as a percent. For solving these kinds of percentage questions, we will first convert the given decimal into a fraction part. After converting the given decimal into fractional part we will use multiplication operation in mathematics and multiply the number $100$ to it and find the answer to the question.

Complete step by step solution:
From the question given we have to express the given decimal number as a percent, given number is,
$\Rightarrow 0.1$
Firstly, as we mentioned earlier, we will convert the given decimal into fraction parts.
$\Rightarrow 0.1=\dfrac{1}{10}$
For any number let it be as \[y\]. We can write the percentage of it which is \[y\%\] into a numerical part as follows.
\[\Rightarrow y\%=y\times \dfrac{1}{100}\]
So, we will do the same to our given number which is $0.1$.
Now for finding the percentage of any number, we should use the multiplication operation in mathematics and multiply it to the number $100$ for which we want the percentage.
Now, in the question we are asked to find percent of $0.1$. So, we will multiply $0.1$ to the $100$ and we will get the required solution.
$\Rightarrow 0.1\%=\dfrac{1}{10}\times 100$
We will simplify the expression further by using the multiplication operation in mathematics.
So, we get expressions reduced as follows.
$\Rightarrow \dfrac{100}{10}$
$\Rightarrow 10\%$

Therefore, $0.1$ as a percent is $10\%$.

Note: Students must be very careful in doing the calculations. Students must have good knowledge in calculating the percentages and also should have knowledge in multiplication operation. If students divide the given number with $100$ instead of multiplying our solution will be wrong.
