Hi there,
\n" ); document.write( "Robin uses 1/4 of a pound of butter
\n" ); document.write( "to make a cake.
\n" ); document.write( "She starts with 7/8 of a pound of butter.
\n" ); document.write( "so she has 7/8 - 1/4 left
\n" ); document.write( "7/8 - 1/4
\n" ); document.write( "Multiply 8 x 4 to get a denominator
\n" ); document.write( "= 32
\n" ); document.write( "Cross multiply 4 x 7 = 28
\n" ); document.write( "and 8 x 1 = 8
\n" ); document.write( "= 28 - 8/ 32
\n" ); document.write( "= 20/32
\n" ); document.write( "Divide top and bottom by 4
\n" ); document.write( "= 5/8 of a pound of butter left.
\n" ); document.write( "Hope this helps. :-)
\n" ); document.write( "
\n" ); document.write( "
