a) НОЗ (16, 8) = 16.
- $$\frac{7}{16} = \frac{7}{16}$$
- $$\frac{3}{8} = \frac{3 \cdot 2}{8 \cdot 2} = \frac{6}{16}$$
б) НОЗ (20, 60) = 60.
- $$\frac{9}{20} = \frac{9 \cdot 3}{20 \cdot 3} = \frac{27}{60}$$
- $$\frac{21}{60} = \frac{21}{60}$$
в) НОЗ (75, 30) = 150.
- $$\frac{12}{75} = \frac{12 \cdot 2}{75 \cdot 2} = \frac{24}{150}$$
- $$\frac{17}{30} = \frac{17 \cdot 5}{30 \cdot 5} = \frac{85}{150}$$
г) НОЗ (20, 25) = 100.
- $$\frac{25}{20} = \frac{5 \cdot 5}{20 \cdot 5} = \frac{125}{100}$$
- $$\frac{55}{25} = \frac{11 \cdot 4}{25 \cdot 4} = \frac{44}{100}$$
д) НОЗ (55, 22) = 110.
- $$\frac{13}{55} = \frac{13 \cdot 2}{55 \cdot 2} = \frac{26}{110}$$
- $$\frac{7}{22} = \frac{7 \cdot 5}{22 \cdot 5} = \frac{35}{110}$$
е) НОЗ (42, 147) = 294.
- $$\frac{55}{42} = \frac{55 \cdot 7}{42 \cdot 7} = \frac{385}{294}$$
- $$\frac{55}{147} = \frac{55 \cdot 2}{147 \cdot 2} = \frac{110}{294}$$
ж) НОЗ (750, 450) = 2250.
- $$\frac{13}{750} = \frac{13 \cdot 3}{750 \cdot 3} = \frac{39}{2250}$$
- $$\frac{7}{450} = \frac{7 \cdot 5}{450 \cdot 5} = \frac{35}{2250}$$
з) НОЗ (225, 375) = 1125.
- $$\frac{21}{225} = \frac{21 \cdot 5}{225 \cdot 5} = \frac{105}{1125}$$
- $$\frac{14}{375} = \frac{14 \cdot 3}{375 \cdot 3} = \frac{42}{1125}$$
