Answer:
F. 75
Step-by-step explanation:
[tex]\frac{1}{1}[/tex] is equal to all the kids in the class.
[tex]\frac{4}{4}-\frac{1}{4}=\frac{3}{4}[/tex] = Kids who did not get an A
[tex]\frac{3}{4}-\frac{1}{3}\\\frac{9}{12}-\frac{4}{12} =\frac{5}{12}[/tex] Kids who did not get an A or a B (got a C)
180 * [tex]\frac{5}{12}[/tex] = 75
75 kids got a C.
Have a nice day!
