\"3%2F4x%2B2%2F5=1\"
\n" ); document.write( "Remember back when you had to add fractions and find the LCD. The worse case was always to multiply the 2 denominators to find a common denominsator. Use that same thinking here. In this case, the LCD is 20x. Rewriting the problem in terms of the LCD, you get:
