Answer
LCM of 54 and 90 is
270
First common multiples: 270, 540, 810, …
270 is divisible by both: 270 ÷ 54 = 5, 270 ÷ 90 = 3 — and 5 and 3 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/54 by 5 and of y/90 by 3.

90 = 2 × 32 × 5

|---|---|---|---|
| 2 | 2 | 2 | 2 |
| 3 | 33 | 32 | 33 |
| 5 | — | 5 | 5 |
— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.
