Impossible to determine without knowing how many points each is worth.
\n" ); document.write( "If you have a 98 and it is worth the same amount as your test, then add 98 and 39 together, and then divide by 2.
\n" ); document.write( "98+39 = 137
\n" ); document.write( "137/2 = 68.5
\n" ); document.write( ".
\n" ); document.write( "However, if the 98 carries a different weight, then you'll average it differently. Can you give us more information?
\n" ); document.write( ".
\n" ); document.write( "Let's say that your 98 average is based on 200 points and your test score is based on 100 points.
\n" ); document.write( "In that case, you would work it this way:
\n" ); document.write( "[(98*point value) + (39*point value)] / total point value
\n" ); document.write( ".
\n" ); document.write( "[(98*200)] + [(39*100)] / 300
\n" ); document.write( "19600 + 3900 / 300
\n" ); document.write( "23500 / 300
\n" ); document.write( "=78.33
\n" ); document.write( "
\n" );
