Jeff and Diana are working on Math homework. Jeff can comlete 4 math problems in 11 minutes. Diana can complete 7 math problems in 25 minutes. Who is faster?
\n" ); document.write( "---------------
\n" ); document.write( "Faster is the most problems per minute.
\n" ); document.write( "4/11 vs 7/25
\n" ); document.write( "4/11 = 0.36 problems/min
\n" ); document.write( "7/25 = 0.28 problems/min
\n" ); document.write( "-------
\n" ); document.write( "Jeff does more problems per minute.
\n" ); document.write( "--------------------
\n" ); document.write( "You can find the common denominator, too
\n" ); document.write( "4/11 = 100/275
\n" ); document.write( "7/25 = 77/275
\n" ); document.write( "100 is more than 77
\n" ); document.write( "----------------
\n" ); document.write( "The inverse is minutes per problem, then the smaller number is faster.
\n" ); document.write( "11/4 = 2.75 mins per problem
\n" ); document.write( "25/7 =~ 3.57 mins per problem
\n" ); document.write( "--------------------
\n" ); document.write( "Maybe Jeff did the easy problems.
\n" ); document.write( " \n" ); document.write( "

\n" );
