The least common multiple of 2.3 and 6 is 6, so 2/3 = 4/6 (up and down are multiplied by 2 at the same time), and 5/6 remains unchanged.
The least common multiple of 3.9 and 8 is 72, so 8 of 9 = 64 of 72 (multiplied by 8 at the same time) and 5 of 8 = 45 of 72 (multiplied by 9 at the same time).
The least common multiple of 4. 4 and 10 are 20, so 3/4 is 15 (multiplied by 5 at the same time) and 9/20 is 18 (multiplied by 2 at the same time).
5. The least common multiple of 10 and 6 is 30, so10 is 3 = 9/30 (multiplied by 3 at the same time) and 1 = 5/30 (multiplied by 5 at the same time).
The least common multiple of 6.7 and 5 is 35, so 2 of 7 = 65438+00 of 35 (multiplied by 5 at the same time), and 7 of 5 = 49 of 35 (multiplied by 7 at the same time).
Least common multiple of 7. 4 and 5 are 20, so 4/4 is 1 = 5/20 (multiplied by 5) and 3/5 = 12 (multiplied by 4).
The least common multiple of 8. 9 and 6 are 18, so 5/9 = 18 (up and down times 2) and 5/6 = 18 (up and down times 3).
