What is the remainder of 245 divided by 9?

Answer 1

27.2222

Answer 2

9 goes into 245 27 times (27 * 9 = 243), with 2 left over, so 2 is the remainder.

---------------------------------------

There is a trick that can be used when finding the remainder when a number is divided by 9:

Add the digits of the number together. If this sum produces a number with more than 1 digit, repeat the summing until a single digit remains. This single digit is the remainder when the original number is divided by 9, except if the single digit is 9 in which case the number is divisible by 9 and the remainder is 0.

for 245:

245 → 2 + 4 + 5 = 11

11 → 1 + 1 = 2

So the remainder when 245 is divided by 9 is 2.

(This single digit is also known as the "digital root" of the number.)
