Помогите решить 1)5ц 7/12 + 1ц 4/8 2)6ц 22/5 - 1ц 1/10 3)4ц 5/7- 1ц 2/3

Answer 1

1) $5frac{7}{12} + 1frac{4}{8} = frac{67}{12} + frac{12}{8} = frac{134}{24} + frac{36}{24} = frac{170}{24} = 7,083$ ц

НОЗ: 24.

2) $6frac{22}{5} - 1frac{1}{10} = frac{52}{5} - frac{11}{10} = frac{104}{10} - frac{11}{10} = frac{93}{10} = 9,3$ ц

НОЗ: 10.

3) $4frac{5}{7} - 1frac{2}{3} = frac{33}{7} - frac{5}{3} = frac{99}{21} - frac{15}{21} = frac{84}{21} = 4$ ц

НОЗ: 21.
