To solve the problem use the formula for area of a triangle...\r
\n" ); document.write( "\n" ); document.write( "Area of a triangle:
\n" ); document.write( "\"A=%281%2F2%29b%2Ah\"\r
\n" ); document.write( "\n" ); document.write( "You may have some difficulty here multiplying mixed numbers. The best option is to convert these. \r
\n" ); document.write( "\n" ); document.write( "A B/C = \"%28A%2AC%2BB%29%2FC\"
\n" ); document.write( "so
\n" ); document.write( "3 5/8 = \"%283%2A8%2B5%29%2F8=29%2F8\"\r
\n" ); document.write( "\n" ); document.write( "You can do the same time thing with 2 1/2.\r
\n" ); document.write( "\n" ); document.write( "For example:
\n" ); document.write( "Same problem different numbers...
\n" ); document.write( "what is the area of a triangle with a base = 4 3/8 and a height = 3 1/2
\n" ); document.write( "\"b=4%263%2F8+=%284%2A8%2B3%29%2F8=35%2F8%29\"
\n" ); document.write( "\"h=3%261%2F2+=%283%2A2%2B1%29%2F2=7%2F2%29\"\r
\n" ); document.write( "\n" ); document.write( "\"A=%281%2F2%29b%2Ah=%281%2F2%29%2835%2F8%29%287%2F2%29=245%2F32\"\r
\n" ); document.write( "\n" ); document.write( "You can leave it in this form or if you need to make it back into a mixed number:
\n" ); document.write( "32 goes into 245 7 times with a remainder of 21. So the answer is 7 21/32.\r
\n" ); document.write( "\n" ); document.write( "

\n" ); document.write( "There are other ways to do this problem as well.
\n" ); document.write( "For instance... we could make the mixed fractions into an addition problems as so...\r
\n" ); document.write( "\n" ); document.write( "4 3/8 = (4+3/8)
\n" ); document.write( "3 1/2 = (3+1/2)\r
\n" ); document.write( "\n" ); document.write( "and then do the following
\n" ); document.write( "
\n" ); document.write( "\"9%2F8+=+8%2F8%2B1%2F8=1%2B1%2F8\" and \"1%2F8=2%2F16\" so \"9%2F8=1%2B2%2F16\"
\n" ); document.write( "So:
\n" ); document.write( "
\n" ); document.write( "\"15%2F2=14%2F2%2B1%2F2=7%2B1%2F2\" and \"1%2F2=16%2F32\" so \"15%2F2=7%2B16%2F32\"
\n" ); document.write( "So:
\n" ); document.write( "\"15%2F2%2B5%2F32=%287%2B16%2F32%29%2B5%2F32=7%2B21%2F32\"
\n" ); document.write( "Which is 7 21/32.
\n" ); document.write( "Pointless but might give some understanding.
\n" ); document.write( "
\n" );
