Answer
LCM of 65 and 100 is
1,300
First common multiples: 1,300; 2,600; 3,900; …
1,300 is divisible by both: 1,300 ÷ 65 = 20; 1,300 ÷ 100 = 13 — and 20 and 13 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/65 by 20 and of y/100 by 13.
65 = 5 × 13
100 = 22 × 52

|---|---|---|---|
| 2 | — | 22 | 22 |
| 5 | 5 | 52 | 52 |
