9/162 = 3/54 = 1/18
The factors of 27 are 1, 3, 9, and 27 The factors of 162 are 1, 2, 3, 6, 9, 18, 27, 54, 81, and 162
The factors of 162 are 1, 2, 3, 6, 9, 18, 27, 54, 81, and 162.
Expressed as a proper fraction in its simplest form, 90/162 is equal to 5/9 or five ninths.
18 / (1/9) = 18 * (9/1) = 162
81: 8 + 1 = 9 which is divisible by 9, so 81 is divisible by 9 162: 1 + 6 + 2 = 9 which is divisible by 9, so 162 is divisible by 9 199: 1 + 9 + 9 = 19 → 1 + 9 = 10 → 1 + 0 = 1 which is not divisible by 9, so 199 is not divisible by 9. 1125: 1 + 1 + 2 + 5 = 9 which is divisible by 9, so 1125 is divisible by 9. So 199 is the only one not divisible by 9.
