Are you certain the 18 wasn’t meant to be just the numeral 18, not 18%?

anyway this is how u do it…

100% = 32 erasers

18% = ?

so wen u multiply 18 X 32 and then divide the answer by 100 you would get 5.76

So if the friend rejected 3 you would be left with 2.76…and wen she gives 2 for the other friend she is left out with 0.76 eraser (which i am guessing is the last 0.25% broken or used eraser) lol..anyway thats ridiculus that they expect a 2nd grader to figure this out!!!

Multiply 32 by .18, because 18% is the same as .18 and 18/100. Add three more after you’ve done that, and then subtract 2. (So really, instead of adding three and then subtracting two, you could just add one.)

I learned how to do this stuff in the sixth grade…
