Question

if a test is worth 75 points and a students earns 60 points what percent did they score ? and how can i calculate a formula to get a answer

Answer 1

Another 2 methods would be to find the lowest common denominator for 60 and 75 i.e. what is a number that will divide exactly into 60 and 75.

Write down all the possible numbers that will equally divide into 60 and 75.

5 and 15.

You can use either 5 or 15 to get to the answer:

5         60/5 =12 over 75/5 =15 >12/15 is there a number that divides equally into 12 and 15? Yes 3 so 12/3 is 4 and 15/3 = 5 > 4/5

     _0.8_

> 5)4.0

 

0.8*100=80%

                                                        _0.8_

15     60/15=4 over 75/15=5 >4/5 ->5)4.0

0.8*100 = 80%

Answer 2

The easiest way to do this is to divide the earned score by the total number of points. Then multiply the answer with a 100 to get the percentage. 

 

60/75=0.8

 

0.8*100=80%
