Question

How do you convert $\dfrac{9}{45}$ into a perceptual decimal?

Answer 1

Hint: As we know in the given problem we have to convert into decimal as formula as
Fraction $=\dfrac{\text{Numerator}}{\text{Denominator}}$
Thus for percentage $=\dfrac{\text{Numerator}}{\text{Denominator}}\times 100%$

Complete step by step solution:
Here in the above numerical we have to convert the number into percent and decimal.
First in the equation we are going to convert into decimal.
Thus we are converting $\dfrac{9}{45}$ in the form of decimal.
Here we have to divide nine by forty five.
Therefore,
Fraction $=\text{numerator}\div \text{denominator}$
So,
$9\div 45=0.2$
Thus when divided we get the decimal values as $0.2$
Secondary in the given question we are going to convert into percent.
Thus when we are making percentage of $\dfrac{9}{45}$
Here we have to convert into decimal and multiplying it with $100$ we get,
Therefore,
Nine divided by forty five and whole multiply by $100$, we have
$\dfrac{9}{45}\times 100=20\%$
So, we get the values as $20\%$

Hence when converted $\dfrac{9}{45}$ into percentage is $20\%$ and decimal as $0.2$

Additional Information:
As we know that we can say that the decimal number is called the fraction with the whole number divided by decimal point.
Here we know that percentage is actually a fraction multiplied to $100$ we get.
Thus we are also taking a general solution of decimal and percentage we get
$\dfrac{1}{6}$
First we are converting it into decimal; we have one divided by six we get.
$1\div 6=0.1666$
Thus when we are taking percentage of $\dfrac{1}{6}$ means fraction into hundred we get,
$\dfrac{1}{6}\times 100=16.66\%$
Hence we get the value of percentage of $16.66\%$

Note: When we are going to take decimal we have to preciouses while dividing and knowing the recurring value if it is greater than five we can round figure by increasing the front value.
Thus when we are making percentage we should have proper fraction i.e. multiply by $100.$
