Question

How do you convert $\dfrac{7}{9}$ into a decimal and percent?

Answer 1

Hint:
So for converting the number or fraction into the percentage we first need to divide the numerator by the denominator and then by multiplying the number with $100$ we will get the result which will be the percentage of the given number. And for decimal, we will just divide the numerator by denominator.

Formula used:
When the number is given in fraction, then
$fraction \times 100\% $
Here, the fraction will be like $\dfrac{8}{9},\dfrac{7}{9},....$

Complete step by step answer:
So we will start by converting the fraction into a decimal and for this, we will divide the numerator by the denominator, so on applying the above steps we get
$ \Rightarrow \dfrac{7}{9} = 0.7777...$
So, after rounding, it will be equal to $0.7778$
Now for getting the percentage, we will multiply the decimal by $100$ and then we will write the result,
So on doing the above step, mathematically it can be written as
$ \Rightarrow 0.7778 \times 100$
And on solving the multiplication, we will get the value as
$ \Rightarrow 77.78\% $

Hence, $\dfrac{7}{9}$ as a percent will be equal to $ \Rightarrow 77.78\% $

Note:
There is one more formula for finding the percentage and in this, we just need \[\]to do the cross multiplication, and on solving it we will get the result. The formula will be
\[\dfrac{{top{\text{ }}of{\text{ }}fraction}}{{bottom}} = \dfrac{{percant}}{{100}}\]
And by substituting the values, we will get the equation as
$ \Rightarrow \dfrac{7}{9} = \dfrac{{percent}}{{100}}$
By performing the cross multiplication, the above equation can be written as
$ \Rightarrow 7 \times 100 = percent \times 9$
Now by taking the constant term to the one side of the equation and solving it we will get the equation as
$ \Rightarrow percent = \dfrac{7}{9} \times 100$
Here this fraction cannot be transferred into simplex form But there are some fraction numbers that can be transferred into simplex form. So we can use this method.
