Go through each of the numbers, and count how many of them are odd. If you count an odd number of them, then their sum is odd. If you count an even number of them, then their sum is even.

there are several ways to do this. Start out looking at them. 9x1=9 odd 9x2=18 even 9x3=27 odd 9x4=36 even 9x5=45 odd 9x6=54 even... so it looks like half might be even and half odd, This is because if we look at the numbers 1-11, ie 1,2,3,4,5,6,7,8,9,10. and 11, they alternate odd and even and since 9 is odd and odd times an even is always an even number and an odd times an odd is always an odd number. So to answer the question we need only look at the number of odd numbers between 1 and 11 inclusive. There are 6 so 1,3,5,7,9,and 11 give odd multiples ANSWER: 6 odd multiples of 9 between 1 and 100
