Question

A class 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 12/100 of the magazines, and Carlita sold 0.095 of the magazines. Who sold the most magazines?

Answer 1

500 total magazines...

Amy sold 1/9......1/9(500) = 500/9 = 55.5
Garret sold 0.145.....0.145(500) = 72.5
Robbie sold 12/100.....0.12(500) = 60
Carlita sold 0.095.....0.095(500) = 47.5

Garret sold the most

or u could have done it this way...
Amy sold 1/9.....1/9 = 11.1%
Garret sold 0.145 = 14.5%
Robbie sold 12/100.....12/100 = 12%
Carlita sold 0.095....0.095 = 9.5%

u will still get the same answer...Garret

Answer 2

Convert all of them into fractions. 
Amy - 1/9
Robbie - 3/25
Garret - 29/200
Carlita - 19/200
What is the common denominator? 
1800
Change the denominators. 
Amy - 200/1800
Robbie - 216/1800
Garret - 261/1800
Carlita - 171/1800
Since Garret's fraction is the greatest, Garret sold the most papers.
