Find Least Common Multiple (LCM) of all denominators.
LCM of 15 and 31 = 465
22 / 15 < 14 / 31
22 ∙ 31 / 15 ∙ 31 < 14 ∙ 15 / 31 ∙ 15
682 / 465 < 210 / 465
False
LCM of 35 and 19 = 665
19 / 35 > 27 /19
19 ∙ 19 / 35 ∙ 19 > 27 ∙ 35 / 19 ∙ 35
361 / 665 > 945 / 665
False
LCM of 25 and 44 = 1100
15 / 25 > 22 / 44
15 ∙ 44 / 25 ∙ 44 > 22 ∙ 25 / 44 ∙ 25
660 / 1100 > 550 / 1100
True
LCM of 25 and 30 = 150
30 / 25 < 29 / 30
30 ∙ 6 / 25 ∙ 6 < 29 ∙ 5 / 30 ∙ 5
180 / 150 < 145 / 150
False
LCM of 15 and 31 = 465
22 / 15 < 14 / 31
22 ∙ 31 / 15 ∙ 31 < 14 ∙ 15 / 31 ∙ 15
682 / 465 < 210 / 465
False
LCM of 35 and 19 = 665
19 / 35 > 27 /19
19 ∙ 19 / 35 ∙ 19 > 27 ∙ 35 / 19 ∙ 35
361 / 665 > 945 / 665
False
LCM of 25 and 44 = 1100
15 / 25 > 22 / 44
15 ∙ 44 / 25 ∙ 44 > 22 ∙ 25 / 44 ∙ 25
660 / 1100 > 550 / 1100
True
LCM of 25 and 30 = 150
30 / 25 < 29 / 30
30 ∙ 6 / 25 ∙ 6 < 29 ∙ 5 / 30 ∙ 5
180 / 150 < 145 / 150
False
