8 is 2 and 1/2 of what number?
\n" ); document.write( "Let x=the number
\n" ); document.write( "2 1/2 is equal to 5/2, so:
\n" ); document.write( "(5/2)x=8 multiply each side by 2
\n" ); document.write( "5x=16 divide each side by 5
\n" ); document.write( "x=3 1/5 = 16/5-------------the number
\n" ); document.write( "CK
\n" ); document.write( "(16/5)(5/2)=8
\n" ); document.write( "8=8
\n" ); document.write( "2/3 divide by 5?
\n" ); document.write( "5/(2/3)=x
\n" ); document.write( "First multiply the numerator and denominator of the left side by (3/2). This will get rid of the complex fraction.
\n" ); document.write( "5*(3/2)/(2/3)*(3/2)=x
\n" ); document.write( "15/2/1=x
\n" ); document.write( "x=15/2=7 1/2
\n" ); document.write( "CK
\n" ); document.write( "(15/2)*(2/3)=5
\n" ); document.write( "5=5\r
