Answer 1

Hint: Here we need to find the percentage marks obtained by Rohit. We will use the formula of percentage to calculate the percentage marks obtained by Rohit. The percentage marks obtained will be equal to the product of the ratio of the marks obtained to the total marks and the number 100. After multiplying the numbers, we will get our required answer.

Formula used:
We will use the formula of percentage given by \[{\rm{percentage}} = \dfrac{{{\rm{value}}}}{{{\rm{total value}}}} \times 100\].

Complete step-by-step answer:
Here we need to need to find the percentage of marks obtained by Rohit.
It is given that marks obtained by Rohit is 45 and the total marks are 80.
So using this formula \[{\rm{percentage}} = \dfrac{{{\rm{value}}}}{{{\rm{total value}}}} \times 100\], we will find the percentage marks obtained by Rohit. Therefore, we get
Percentage of marks obtained by Rohit \[ = \dfrac{{45}}{{80}} \times 100\]
On multiplying the numbers, we get
Percentage of marks obtained by Rohit \[ = 56.25\% \]
Hence, the required percentage of marks obtained by Rohit is equal to \[56.25\% \]

Note: Since we have calculated the percentage of marks obtained by Rohit. The percentage formula is used to find the value of something in terms of 100. We need to keep in mind that the percent means per hundred. The percentage formula is used to express a number between the number zero and one. It can also be expressed in the form of decimal numbers.
In real life, we use percentage to express the marks obtained by a student, to calculate the increment or decrement of salary, population, etc.
