Homework questions
489 divided by 89
7 and 3/7 subtract 2 and 4/5
Is it just me, or are those ridiculous examples to give as homework?
Surely, as a teacher you work out the inverse first to check your answer is one they can aim for (so say, 306 divided by 24 is 12.75) so they are able to practice their long division skills?
As for the fractions one. Don't have an issue with finding the LCM of 35 but it ends up being large mixed numbers with a lot of dividing etc. Surely we should just be doing things like 7 and 3/4 minus 5 and a third (or something!)
