(11/18) - (1/6) = (11/18) - (3/18) = (11-3)/18 = 8/18 = 4/9
= (19/12)/(11/4) =19/12 * 4/11 =19/3 * 1/11 =19/33
11/18 - 1/6 = 11/18 - 3/18 = 8/18 = 4/9
The factors of 10 are: 1, 2, 5, 10 The factors of 11 are: 1, 11 The factors of 12 are: 1, 2, 3, 4, 6, 12 The factors of 13 are: 1, 13 The factors of 15 are: 1, 3, 5, 15 The factors of 16 are: 1, 2, 4, 8, 16 The factors of 17 are: 1, 17 The factors of 18 are: 1, 2, 3, 6, 9, 18 The factors of 19 are: 1, 19 The factors of 20 are: 1, 2, 4, 5, 10, 20
19/3 = 18/3 + 1/3 = 6 + 1/3 = 61/3
1 + 18 = 19, 2 + 17 = 19, etc. 10 + 9 = 21 correct
(11/18) - (1/6) = (11/18) - (3/18) = (11-3)/18 = 8/18 = 4/9
11: 1, 11 12: 1, 2, 3, 4, 6, 12 13: 1, 13 14: 1, 2, 7, 14 15: 1, 3, 5, 15 16: 1, 2, 4, 8, 16 17: 1, 17 18: 1, 2, 3, 6, 9, 18 19: 1, 19 20: 1, 2, 4, 5, 10, 20
1, 2, 3, 6, 9, 18 1, 19
= (19/12)/(11/4) =19/12 * 4/11 =19/3 * 1/11 =19/33
The factors of 57 are 1, 3, 19, and 57The factors of 18 are 1, 2, 3, 6, 9, and 18
11/18 - 1/6 = 11/18 - 3/18 = 8/18 = 4/9
The factors of 10 are: 1, 2, 5, 10 The factors of 11 are: 1, 11 The factors of 12 are: 1, 2, 3, 4, 6, 12 The factors of 13 are: 1, 13 The factors of 15 are: 1, 3, 5, 15 The factors of 16 are: 1, 2, 4, 8, 16 The factors of 17 are: 1, 17 The factors of 18 are: 1, 2, 3, 6, 9, 18 The factors of 19 are: 1, 19 The factors of 20 are: 1, 2, 4, 5, 10, 20
19/3 = 18/3 + 1/3 = 6 + 1/3 = 61/3
18. 1 and18 add to 19, 2 and 9 add to 11, and 3 and 6 add to 9.
1, 11 1, 3, 19, 57
19/3 x 11/6 = 209/18 or 11 and 11/18
