Question

0.07 is equal to how much percent?
$A)70\% $
$B)7\% $
$C)0.7\% $
$D)0.07\% $

Answer 1

Hint: The concept of the percentage, which means a number or a given ratio will be represented in the form of fractions of $100$
The percentage is the relative value that will indicate the hundredth parts of a given quantity.
Like $70\% of 40 = 28$ here, seventy is the percent and fourth is the base and twenty-eight is the part.

Complete step-by-step solution:
Since the number is $0.07$ and then we need to find the percentage of this number.
Also, we know that Once the fraction of the number is found, we will multiply it with the number $100$ to get the percentage form of the required answer.
Hence, we have $0.07 \times 100$ will get the resultant.
Further solving we have $0.07 \times 100 = 0.7 \times 10$ because $0.1 \times 10 = 1$
Again, solving with the multiplication, we get $0.07 \times 100 = 0.7 \times 10 \Rightarrow 7$
Therefore $0.07$ is equals to $7\% $
Additional information:
What percentage is $13$ week for one year?
it is a predetermined fact that one year contains $52$ weeks
Therefore, the number of weeks in the one year is $52$ weeks.
Hence applying the unitary method (converting years into weeks), we have the number of years $1$ week can be represented as $1W = \dfrac{1}{{52}}Y$ (years)
Now multiplying both sides with the number $13$ to obtain the $13$ weeks of one year. Then we get $13W = \dfrac{{13}}{{52}}Y$ and by division operation we get $13W = \dfrac{1}{4}Y$
Thus, to find its percentage value we will multiply it with the number $100$ to get the percentage form of the required answer. Hence, we have $\dfrac{1}{4} \times 100 = 25\% $
Hence, we will conclude that the percentage of $13$ weeks of one year is $25\% $.

Note: The concept of Percentage is used to find the given share or amount of something in terms of $100$. Since the percentage formula is: Percentage = given value divided by total value $ \times 100$. Since we have to remember the number of weeks, months, and days in one year and hence it is easy to solve as above. We also used the basic unitary method to obtain the required answer. We are also able to use the direct formula of the required percentage using the percentage formula.
