help got a test in 2 days and i am studying math after 30 years

A student receives his grade report from a local community college, but the GPA is smudged. He took the following classes: a 2 hr. credit art, a 3 hr credit history, a 4 hr credit science course, a 3 hr credit mathematics course, and a 1 hr science lab. He received a B in the art class, an A in the history class, a C in the science class, a B in the maths class, and an A in the science lab. What was his GPA if the letter grades are based on a 4 point scale? (A=4, B=3, C=2, D=1, F=0)?

And would this be a question finding averages. Help please.

Multiply each grade's value with the number of credits associated with the course.
Art was worth 2 credits and he scored a B, so we do 2 x 3 = 6.

Do this for the other four courses and add up all the "credit-grades".
Then find the total amount of credits and divide the first answer by that.

This is a nice question, because the average you get is a whole number and so can be easily converted back into a letter grade.

Why did the vector cross the road?
It wanted to be normal.

The method describe by mathys... is fine...we get a total of 39 credits earned by the guy out of 52 (maximum)...dividing 39/52 gives gives 0.75 ..... for 10 scale it becomes 7.5 and for 4 scale it will be 4*0.75 which is 3....................it is lik if a guy gets 7.5 out of 10 wat will he get out of 4...........
