I know when dividing fractions the second set you flip and then it becomes multiplication. But what if you have three sets??\r
\n" ); document.write( "\n" ); document.write( "8/21 / (-4/7) / 4/3\r
\n" ); document.write( "\n" ); document.write( "It all depends on how you group the fractions.
\n" ); document.write( "Let's look at a simple example: 40/2/5
\n" ); document.write( "If you do 40/2 first and then divide by 5 you get 20/5 = 4.
\n" ); document.write( "If you do 2/5 first then divide that into 40 you get $\"40%2F%282%2F5%29+=+40%2A%285%2F2%29+=+100\"$ .\r
\n" ); document.write( "\n" ); document.write( "In general, if you have $\"%28a%2Fb%29%2Fc\"$ then multiply numerator (a/b) and denominator (c) by 1/c to get $\"%281%2Fc%29%28a%2Fb%29+=+a%2F%28bc%29\"$ .\r
\n" ); document.write( "\n" ); document.write( "If you have $\"a%2F%28b%2Fc%29\"$ then multiply numerator (a) and denominator (b/c) by c/b to get $\"a%28c%2Fb%29+=+ac%2Fb\"$ .\r
\n" ); document.write( "\n" ); document.write( "So, see if you can now do the problem. Let me know if you can't. \n" ); document.write( "
