- One way to go about this might be to list all the 90
possibilities. In other words, 10 divided by 1+0 is 10 with
a remainder of 0; 11 divided by 1+1 is 5 with a remainder of 1,
and so forth all the way up to 99.
- But a little thought might give a more systematic approach.
Remember, when you divide one number by another, the remainder is
always less than the divisor (the number you divide by).
As always, be sure to explain the
work you did to arrive
at your answers!
