Allie sold about 71 magazines.
Gary sold about 43.
Rob sold about 45.
Felisha sold about 93.
Felisha sold the most magazines.
Elaboration:
Since Allie sold 1/7 of the 500 magazines, you must find 1/7 of 500. To do this, multiply 500 by the numerator, which is 1. Now you have
, which is the same thing as dividing 500 by 7, which is around 71.
Since Gary sold 0.085 of the magazines, you multiply this decimal by that same 500, getting about 43.
Since Rob sold 9/100 of the magazines, you once again multiply 500 by the numerator, coming out with 4,500. Then you replace the 9 with that number, so you have
, which is also the same thing as Allie's in the fact that you're dividing 4,500 by 100, which is 45. Therefore, Rob sold 43 magazines.
Since Felisha sold 0.185 of the magazines, you follow the same procedure as with Gary - multiply the decimal by 500, getting 93.
Hope this helps! Live long and prosper, my friend. :)
