Andy takes a computer course exam. he scores 53 marks out of 75. work out andys percentage score to 1 decimal place

Hello there!

Andy scores 53 marks out of 75, and we want to know the percentage score of Andy.

if 75 marks are 100%, now we want to calculate the percentage correspondent of 53 marks, to do this we need to divide the number of marks that Andy gets by the total amount of marks, and multiply it by 100%.

this is (53/75)*100% = 0.70666..*100% = 70.666%

and we want this to a decimal place, so we need to round it up because the second number after the decimal point is a 6.

then the score of Andy is 70.7%

depends on how many days you are talking about

step-by-step explanation:

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
