You can put this solution on YOUR website!
You have \"%285%2F8%29%2F%285%2F4%29\"= \"y%2F%283%2F2%29\"\r
\n" ); document.write( "\n" ); document.write( "To cross multiply we multiply the denominators (5/4) and (3/2) to the opposite sides (creating a cross) like so:
\n" ); document.write( "---------
\n" ); document.write( "step 1: take (5/4) to the right by multiplying (5/4) on both sides
\n" ); document.write( "\"%285%2F4%29%2A%285%2F8%29%2F%285%2F4%29\"= \"%285%2F4%29%2Ay%2F%283%2F2%29\"\r
\n" ); document.write( "\n" ); document.write( "(5/4)/(5/4) on the left cancel each other out because it equals 1\r
\n" ); document.write( "\n" ); document.write( "\"%285%2F8%29=%285%2F4%29%2Ay%2F%283%2F2%29\"
\n" ); document.write( "---------
\n" ); document.write( "step 2: take (3/2) to the left by multiplying (3/2) on both sides
\n" ); document.write( "\"%283%2F2%29%2A%285%2F8%29=%283%2F2%29%2A%285%2F4%29%2Ay%2F%283%2F2%29\"\r
\n" ); document.write( "\n" ); document.write( "(3/2)/(3/2) on the right cancel each other out because it equals 1
\n" ); document.write( " \"%283%2F2%29%2A%285%2F8%29=%285%2F4%29%2Ay\"
\n" ); document.write( "---------
\n" ); document.write( "step 3: simplify the left by multiplying numerators and denominators (top and bottom)\r
\n" ); document.write( "\n" ); document.write( "\"%283%2A5%29%2F%282%2A8%29=%285%2F4%29%2Ay\"\r
\n" ); document.write( "\n" ); document.write( "\"15%2F16=%285%2F4%29%2Ay\"
\n" ); document.write( "---------
\n" ); document.write( "step 4: solve for y by multiplying by 4 and dividing by 5 on both sides(also known as multiplying by the reciprocal fraction (4/5)) \r
\n" ); document.write( "\n" ); document.write( "\"%2815%2F16%29%2A%284%2F5%29=y%2A%285%2F4%29%2A%284%2F5%29\"\r
\n" ); document.write( "\n" ); document.write( "\"%28%2815%2A4%29%2F%2816%2A5%29%29=%28%285%2A4%29%2F%284%2A5%29%29%2Ay\"\r
\n" ); document.write( "\n" ); document.write( "\"%28%2815%2A4%29%2F%285%2A16%29%29=%28%285%2A4%29%2F%285%2A4%29%29%2Ay\"\r
\n" ); document.write( "\n" ); document.write( "\"%2815%2F5%29%2A%284%2F16%29=+%285%2F5%29%2A%284%2F4%29%2Ay\"\r
