If you are saying that you have no homework results but you want to maintain
the same relative weighting between quiz and tests, just divide your
original answer by 90%.

we created a spreadsheet for our kids grades, ie.

we show quiz 15%, homework 10% and tests 75%.

how do we average and weight the grade (and show the formulae) if there
were
no homework grades.

thanks,
