If "d" divided by 7 has a remainder of 1, which of the following divided by 7 has a remainder of 6?

Answer 1

the choices are:
1. d-6
2. d-5
3. d-4
4. d-3
5. d-2

Answer 2

differences of ±7 leave the remainder unchanged. That means that since we want to increase the remainder by 5, we can either add 5 or subtract 2 (add 5 and subtract 7) from the number.

d-2
