Worksheet Overview

QUESTION 1 of 10

Starting at 0 we can count up in 9s like this:

0    9    18    27    36    45    54    63    72    81    90    99    108 ...

 

We add 9 to the previous number to get the next.

These are the multiples of 9.

 

Notice that the digits of each multiple add up to 9 or a multiple of 9

(2 + 7 = 9,   4 + 5 = 9,   9 + 9 = 18,   1 + 0 + 8 = 9  etc.)
