Depends. Usually, 90-100 is an A 80-89 is a B 75-79 is a C 70-74 is a D and 69 and below is usually an F
89/100 or .89
0.89
.89 is equivilant to 89/100
Range = 89 - 78 = 11
89-15 = 74
15 + 74 = 89.
It is 18.
Assuming all questions are worth the same amount of points, the answer is you can miss 23.14 problems, or rounded, 23 problems, which makes more sense.Here is the work, it's fairly elementary, so I won't explain each step:Let n be the number of problems you can miss.(89-n) / 89 = 74 / 100

The GCF is 1.
That basically means what is 89+100. 89+100=189.
0.89
89/100
89 - 57 = 32
89/100.
