Let a, b, and c be her scores on the first three quizzes and dd and ee be her scores on the next two quizzes. Since she scored an average of 8 correct answers on her first three quizzes, then: average=(sum of first three quiz scores/3 quizzes)

I am at a complete loss as to where to even start this mathproblem.
102 2/5 - 43 3/4
The only thing I get is that I'm to subtract the whole numbersfirst. After that I am completely stumped as to what comes next. Itried finding the least common denominator for 4 and 5, but I couldonly come up with the number 1 for both of them. If anyone couldhelp explain the general idea of where to go from here, I wouldtruly appreciate it! Thank you!

Imagine cutting a sphere into circles(the distance between the two circles is almost zero).
Then is it correct to say that the sum of the circumference of all the circles is the surface area of the sphere? (Please describe why not)
(Where is radius in each circle with distance h to center, Also multiplied by 2 because it's sum of circles in semisphere)Thanks in advance.
