Aclass is selling magazines as a fund raiser. of the 500 magazines sold, amy sold 1/9 of them. garret sold 0.145 of the magazines. robbie sold 11/100 of the magazines, and carlita sold 0.095 of the magazines. who sold the most magazines?

Not Amy because 1/9 means 1 out of 9 if you do 9*50 you get 450 and that's good because there is 50 more because we did out of 9 not 1/10. At the end if you do 1*50 because you did 9*50 to get the answer you get 50.

Garret because .145*500 gives you 72.5 which we can round to 72 or 73. We multiply by 500 because it only gives us .145 and they are no limitation like Amy which is only 9. Garret delay .145 of 500 which is again either 72 or 73.

it's not Robbie because he sells 55. We get 55 because if he is selling 11 every 100 magazines then we can multiply it by 5 and get a fraction of 55/500 or just 55.

Not Carlita because she is only selling 47.5 which we could round to 47 or 48. You get this if you multiply .095 by 500. We are multiplying by 500 because just like Garret we have no limitation unlikely Robbie who has only 11/100 and Amy who has 1/9.

So the winner is Garret. Home you understand.
