9/10 and 7/8\r
\n" ); document.write( "\n" ); document.write( "to add these items together you must find a comon denominator in this case an easy denominator is 80,\r
\n" ); document.write( "\n" ); document.write( "multiply 9/10 by 8 to get 72/80
\n" ); document.write( "multiply 7/8 by 10 to get 70/80\r
\n" ); document.write( "\n" ); document.write( "now you can add them together to get 142/80 you can divide the top by 2 to find the answer\r
\n" ); document.write( "\n" ); document.write( "142/2=71\r
\n" ); document.write( "\n" ); document.write( "so 71/80 is your answer.
