LCM of 10 and 55 is
110
First common multiples: 110, 220, 330, …
110 is divisible by both: 110 ÷ 10 = 11, 110 ÷ 55 = 2 — and 11 and 2 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/10 by 11 and of y/55 by 2.

| 5 | 5 | 5 | 5 |
| 11 | — | 11 | 11 |
— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.
