Answer
The student's mark is 65%.
Solution
To express the student's mark as a percentage, we need to divide the student's mark by the total possible marks and then multiply by 100.
Given:
Student's mark = 78
Total possible marks = 120
Percentage = (Student's mark / Total possible marks) * 100
Let's calculate the percentage.
Calculate the value by following steps:
- step0: Calculate:
\(\left(\frac{78}{120}\right)\times 100\)
- step1: Reduce the fraction:
\(\frac{13}{20}\times 100\)
- step2: Reduce the numbers:
\(13\times 5\)
- step3: Multiply the numbers:
\(65\)
The student's mark as a percentage is 65%.

Simplify this solution The Deep Dive
To express the student's mark as a percentage, you can use the formula: (Marks Obtained / Total Marks) × 100. In this case, it's (78 / 120) × 100. Doing the math gives you 0.65, and then multiplying by 100 results in 65%. So, the student scored 65%! Another fun fact: percentages are often used in day-to-day life without us realizing it! Whether you're calculating discounts during a sale, figuring out your grades, or even managing your budget, understanding how to work with percentages can make life a whole lot easier and ensure you maximize your savings!
