Hello!
\n" ); document.write( "This can be solved dividing 5/16 by 7/18. If the answer is greater than 1, it means that 5/16 is greater than 7/18. If the answer is less than 1, then we'll conclude that 5/16 is smaller than 7/18.\r
\n" ); document.write( "\n" ); document.write( "So we have:
\n" ); document.write( "\"%285%2F16%29%2F%287%2F18%29\"\r
\n" ); document.write( "\n" ); document.write( "Nowm recall that dividing by a fraction is the same as multiplying by its inverse. So we get that the above expression is the same as:
\n" ); document.write( "\"%285%2F16%29%2818%2F7%29\"\r
\n" ); document.write( "\n" ); document.write( "Now simplify the 16 and the 18 dividing them by 2, to get:\r
\n" ); document.write( "\n" ); document.write( "\"%285%2F8%29%2A%289%2F7%29\"\r
\n" ); document.write( "\n" ); document.write( "The result of this multiplication is:
\n" ); document.write( "\"%285%2A9%29%2F%288%2A7%29=45%2F56\"\r
\n" ); document.write( "\n" ); document.write( "Since this fraction is smaller than 1 (because 45 is smaller than 56) we conclude that 5/16 is smaller than 7/18.\r
