QUESTION:-

How to convert the mark 20 to 15?

GIVEN:- Marks 20

TO FIND:- Convert the mark 20 to 15

SOLUTION:-

• In mathematics, a number or ratio expressed as a fraction of 100 is called a percentage
• Assuming the total number of marks as 30

Step 1:- Calculate the percentage of 20 marks obtained

As we know, Percentage =

$\frac{value}{total \: value} \times 100$

According to sum,

$= \frac{marks \: obtained}{total \: marks} \times 100$

By putting values in the formula

$= \frac{20}{30} \times 100 \\ = 66.67\%$

Step 2:- We need to find 66.67% of 15

$= \frac{66.67}{100} \times 15 \\ = \frac{1000.05}{100} \\ = 10.005$

HENCE, MARKS OBTAINED = 10
