Общий знаменатель дробей: 123/93и456/54 666/56и1028/72 79/90и97/9 7924/7и299/45

Answer 1

123/93 и 456/54

НОК(93,54)=1674

93 = 3 · 31

54 = 2 · 3 · 3 · 3

$\frac{123}{93} = \frac{2214}{1674}$

$\frac{456}{54} = \frac{14136}{1674}$

666/56 и 1028/72

НОК(56,72)=504

56 = 2 · 2 · 2 · 7

72 = 2 · 2 · 2 · 3 · 3

$\frac{666}{56} = \frac{5994}{504}$

$\frac{1028}{72} = \frac{7196}{504}$

79/90 и 97/9

НОК(90,9)=90

90 = 2 · 3 · 3 · 5

9 = 3 · 3

$\frac{79}{90} = \frac{79}{90}$

$\frac{97}{9} = \frac{970}{90}$

7924/7 и 299/45

НОК(7,45)=315

7 = 7

45 = 3 · 3 · 5

$\frac{7924}{7} = \frac{356580}{315}$

$\frac{299}{45} = \frac{2093}{315}$
