Question

What is $\dfrac{15}{25}$ as a decimal and percent?

Answer 1

Hint: For solving this question you should know about decimal and percent values and how to calculate the decimal numbers of any numbers. We will calculate the decimal value of $\dfrac{15}{25}$ in this question and we will first take both as a fractional form for decimal value and then we will calculate the decimal value. And also know how to calculate any value whose percentage is given to us. And it is calculated by a formula which is used to convert the percentage from any value. The general formula is given as, percentage (\%) = $\dfrac{\text{value}}{\text{total value}}\times 100$.

Complete step by step solution:
According to our question we have to calculate the decimal and percent of $\dfrac{15}{25}$. For calculating the decimal value of any value we always divide it with 10 and if it is given in any form, we solve that first and then bring it to a form of $\dfrac{x}{10}$. And if we have to calculate the decimal value of any value then according to mathematics, the meaning of ‘of’ is equal to multiplication. So, we multiply both with one another and then we get the decimal value. The general formula is, percentage (\%) = $\dfrac{\text{value}}{\text{total value}}\times 100$.
Thus, we can calculate the percentage of any number and the number and the total value of that by a single formula. The percentage is the amount of something in terms of 100. And we can say that the percent means per hundred. It means what the value or amount is at every $\text{hundre}{{\text{d}}^{th}}$.
According to the question, the decimal form is,
$\dfrac{15}{25}=0.6$
And to get percentage,
$\Rightarrow \dfrac{15}{25}\times 100=0.6\times 100=60\%$

So, the decimal is 0.6 and the percent is 60\%.

Note:
For calculating the decimal value of any fractional number you have to be assured that the number contains a denominator of 10 and the power of 10. And if the denominator is not in this form, then we have to make it in this form always. The percentage denotes how much any value is available or contained in the 100 of the value for which the percentage is going to be calculated. In mathematics the percentage is a number or a ratio that represents a fraction of 100.
