Ответ:
- \(НОК(12,8)=24\): \(\frac7{12}=\frac{14}{24}\), \(\frac58=\frac{15}{24}\).
- \(НОК(9,15)=45\): \(\frac29=\frac{10}{45}\), \(\frac4{15}=\frac{12}{45}\).
- \(НОК(25,15)=75\): \(\frac7{25}=\frac{21}{75}\), \(\frac2{15}=\frac{10}{75}\).
- \(НОК(16,24)=48\): \(\frac3{16}=\frac9{48}\), \(\frac5{24}=\frac{10}{48}\).
Ответ: 1) НОК = 24, \(\frac{14}{24}\) и \(\frac{15}{24}\); 2) НОК = 45, \(\frac{10}{45}\) и \(\frac{12}{45}\); 3) НОК = 75, \(\frac{21}{75}\) и \(\frac{10}{75}\); 4) НОК = 48, \(\frac9{48}\) и \(\frac{10}{48}\).
