if u have a test and its worth 30 points then how would u calculate on the

[Shishi Rocks]

calculator to see what your grade? how would you do it on the calculator to find out the grade 30 points out of 28

 

[KoKo KiTTy]

28 x 100 divided by 30 would be the percentage you make

 

[Gymnast1995]

or you could just divide 28 by the 30

 

[NellyE]

first divide what you got (28) into the total marks (30); which will give you 0.93333. Then multiply by 100 for a percentage, giving 93.333333%

basically that should be an A / A* for a grade...but check with your teacher what the percentage you need is for each grade
