How do I add these numbers together and divide by 2 to find a real number?
\n" ); document.write( "7/8 and 9/10
\n" ); document.write( "-----------
\n" ); document.write( "Get the same denominator on both fraction:
\n" ); document.write( "The least common multiple of 8 and 10 is 40
\n" ); document.write( "Rewrite each fraction with 40 as its denominator:
\n" ); document.write( "7*5/8*5 + 9*4/10*4
\n" ); document.write( "=35/40 + 36/40
\n" ); document.write( "=71/40
\n" ); document.write( "Now, divide by 2:
\n" ); document.write( "[71/40]/2
\n" ); document.write( "=71/[40*2]
\n" ); document.write( "=71/80
\n" ); document.write( "Cheers,
