Answer 1

- Hint:-In this question first we have to convert the given ratio (3:4) into the fraction form. Then multiply the obtained form of fraction by 100 to get the conversion of the given ratio (3:4) to the percentage form.

Complete step-by-step solution -

A percentage is a fraction with denominator 100 i.e.$\dfrac{1}{{100}}$.
“Percentage” is derived from Latin word “per centum” which means per hundred as we defined in the above definition.
It is denoted by the% symbol.
1 percentage (%) means $\dfrac{1}{{100}}$=0.01
For conversion a ratio into a percentage first convert it into fraction form by changing “:'' into “/” for example a:b can be written in fraction as a/b. Then, multiply the fraction by 100 and add % symbol to the result.
Given ratio is 3:4
On converting the given ratio into fraction we get
$ \Rightarrow 3:4 = \dfrac{3}{4}$
Now, multiply the obtained fraction by 100, we get
$
   \Rightarrow \% {\text{ of 3:4 = }}\left( {\dfrac{3}{4} \times 100} \right)\% \\
   \Rightarrow \% {\text{ of 3:4 = }}\left( {3 \times 25} \right)\% \\
   \Rightarrow \% {\text{ of 3:4 = 75% }} \\
$
Hence, the conversion of 3:4 into percentage is 75%.
