From our divisibility calculator, we see a number is divisible by 9 if the sum of its digits is divisible by 9.

Starting from 1 to 99, we find all numbers with a digit sum of 9.

This would be digits with 0 and 9, 1 and 8, 2 and 7, 3 and 6, and 4 and 5.

27

36

72

81

90

Now remove even numbers since the problem asks for odd numbers

9

81

Now, divide each number by 10, and find the remainder

9/10 = 0

27/10 = 2 R 7

We stop here.

**27**is an odd number, less than 100, with a remainder of 7 when divided by 10.
