Manny can throw a football exactly 36 yards and Tony can throw a football exactly 30 yards.
\n" ); document.write( "If they start to throw their football from the same spot, what is the minimum
\n" ); document.write( "number of throws for Tony so that the footballs would have been thrown the same distance?
\n" ); document.write( ":
\n" ); document.write( "Find the least common multiple
\n" ); document.write( "Factor 36: 2*2*3*3
\n" ); document.write( "Factor 30: 2*3*5
\n" ); document.write( "LCM: 2*2*3*3*5 = 180
\n" ); document.write( ":
\n" ); document.write( "\"what is the minimum number of throws for Tony so that the footballs would have been thrown the same distance? \"
\n" ); document.write( "180/30 = 6 throws for Tony (5 throws for Manny) \n" ); document.write( "

\n" );
