Question

What is \[70\%\] of \[70\]?

Answer 1

Hint: In order to find \[70\%\] of \[70\], we have to multiply \[70\%\] with \[70\], which gives us the \[{{70}^{th}}\] part of \[70\] when \[70\] is divided into hundred equal parts. Since it is given as percent, we will be calculating the total parts as hundred. We can also consider \[70\] as a whole because it would be divided into hundred equal parts.

Complete step by step solution:
Let us learn about calculating percentages. Percent means nothing but per every hundred. Firstly, determine the total or complete amount. Next we have to divide the number that is to be expressed as a percent by the total. Generally, in most of the cases we will be dividing the smaller number by the larger number. Lastly, we have to multiply the result with hundred and we can obtain the required result.
Now let us calculate the \[70\%\] of \[70\].
This can be expressed mathematically as shown below-
\[\dfrac{70}{100}\times 70\]
Now let us solve it accordingly.
\[\begin{align}
  & \Rightarrow \dfrac{70}{100}\times 70 \\
 & =0.7\times 70 \\
 & =49 \\
\end{align}\]

\[\therefore \] The \[70\%\] of \[70\] is \[49\].

Note: We have solved \[\dfrac{70}{100}\] first. But it can also be solved in another way i.e. we can multiply \[70\] and \[70\] at first and then we can divide the result by hundred as shown below.
\[\begin{align}
  & \Rightarrow \dfrac{70}{100}\times 70 \\
 & =\dfrac{4900}{100} \\
 & =49 \\
\end{align}\]
We can observe that we obtain the same result in both of the cases, so any of the methods can be preferred accordingly. Percentages are applicable in our everyday life in calculating the grades or scores, in calculating the profit or loss percentage, discount percentage also the blood content in a body and many more.
