Algebra.Com's Answer #217130 by JBarnum(2146)![]() ![]() You can put this solution on YOUR website! if u have 3 out of 10 things its expressed 3/10 so if u have R and G out of 7 it would be R/7 and G/7 \n" ); document.write( "theres 23 total spins 8/23 spins land on red \n" ); document.write( "theres 7 total sections R/7 sections are red \n" ); document.write( "so \n" ); document.write( " |
