You can put this solution on YOUR website!
When add or subtract fraction, the denominators must be the same. That is not the case when you multiply or divide.\r
\n" ); document.write( "\n" ); document.write( "If I asked you to multiply \"1%2F3\" * \"1%2F2\" = \"1%2F3+%2A+1%2F2\" you would say \"1%2F6\". No need to get a common denominator. Just multiply the numerators together. Then put that result over the product of the denominators. Then simplify if possible.\r
\n" ); document.write( "\n" ); document.write( "So let;s do the first one.
\n" ); document.write( "\"%2816x%5E2%2Fy%5E4%29+%2A+%285x%5E2%2Fy%5E2%29\"
\n" ); document.write( "\"%2816x%5E2+%2A+5x%5E2%29+%2F%28y%5E4+%2A+y%5E2%29\"
\n" ); document.write( "\"%2880x%5E2+%2A+x%5E2%29+%2F%28y%5E6%29\"
\n" ); document.write( "\"80x%5E4++%2Fy%5E6\"\r
\n" ); document.write( "\n" ); document.write( "I'll leave problem 2 for you.\r
\n" ); document.write( "\n" ); document.write( "Let's look at problem 3.
\n" ); document.write( "\"%28%28x%5E2%2B7x%2B12%29%2F%28x%2B4%29%29+%2A%281%2F%28x%2B3%29%29\"
\n" ); document.write( "\"%28%28x%2B4%29%28x%2B3%29%2F%28x%2B4%29%29+%2A%281%2F%28x%2B3%29%29\"
\n" ); document.write( "\"%28x%2B3%29+%2A+%281%2F%28x%2B3%29%29\"
\n" ); document.write( "\"1\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "To do division, just remember that dividing a fraction by a fraction is the same as multiplying the first fraction by the reciprocal of the second one.\r
\n" ); document.write( "\n" ); document.write( "So, for problem 4
\n" ); document.write( "\"%28%2825xy%5E2%29%2F7z%29+%2F%28%285x%5E2y%5E2%29%2F14z%5E2%29\"
\n" ); document.write( "\"%28%2825xy%5E2%29%2F7z%29+%2A+%2814z%5E2%2F%285x%5E2y%5E2%29%29\"
\n" ); document.write( "And now use the same process used in the previous problems to solve. \r
\n" ); document.write( "\n" ); document.write( "Same for 5. Just remember to factor and cancel before getting too far into the work
\n" ); document.write( "
