Alyssa says it is easier to compare the numbers in set a (45,760 and 1,025,680) than the numbers in set b(492,111 and 409,867). what is one way you could construct an argument justifying whether alyssa's conjecture is true?

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
