You can put this solution on YOUR website!
Change your numbers into fractions.
\n" ); document.write( " $\"4%2B1%2F4=17%2F4\"$
\n" ); document.write( " $\"1%2B1%2F3=4%2F3\"$
\n" ); document.write( "When adding and subtracting fractions, you need to have the same denominator.
\n" ); document.write( "The quickest way is find the product of the denominators and change all the fractions to match.
\n" ); document.write( "In this case, the product is 3x4=12.
\n" ); document.write( " $\"%2817%2F4%29%2A%283%2F3%29=51%2F12\"$
\n" ); document.write( " $\"%284%2F3%29%2A%284%2F4%29=16%2F12\"$
\n" ); document.write( "Now we can put it all together,
\n" ); document.write( " $\"4%2B1%2F4-%281%2B1%2F3%29=17%2F4-4%2F3\"$
\n" ); document.write( " $\"4%2B1%2F4-%281%2B1%2F3%29=51%2F12-16%2F12\"$
\n" ); document.write( " $\"4%2B1%2F4-%281%2B1%2F3%29=35%2F12\"$
\n" ); document.write( "Since 12 and 35 do not have any common factors, your answer is in lowest terms.
\n" ); document.write( "Your answer is 35/12 or 2 11/12. \n" ); document.write( "

\n" );
