where is the ratio for the 12th graders

4itc · Answer

ah i see

i think that you might have to make the last number of the two ratios the same, and then the higher first number is the answer

so like the number of 11th graders would be like 222:225 but im not that good with math :P

4itc · Answer

it could also be e cuz they didnt give the 12th graders. didnt even consider that...

4itc · Answer

originally i thought a or c... but there's no info for c... im going with E now.
unless you have to do math to find the ratio for 12th graders
