when 20 is divided by a positive integer n, the remainder is 2. how many possible values are there for n?
6 answers
3, 6, 9
How do you get those answers, could you show a step by step ?
Since there is a remainder of 2 when 20 is divided by n, it means that there would be a remainder of 0 when 18 is divided by n.
So, n is a divisor of 18.
That is, 3,6,9
So, n is a divisor of 18.
That is, 3,6,9
Okay thank you so much!!!
3,6,9 and 18, since 20/18 also has a remainder of 2.
ouch. nice catch.
PS:
Also, though 2 is a divisor of 18, it's not a possible value of n, since it also divides 20 evenly.
