Question

1) 1 11/14+2 5/14
2) 8-5 7/8
3) 2 1/9-1 1/3
4) 3 1/6-2 1/12

Answer 1

Ответ:

$2\frac{1}{7}; 2\frac{1}{8}; \frac{5}{6}; 1\frac{1}{12}$

Пошаговое объяснение:

$1)1\frac{11}{14} +2\frac{5}{14} =\frac{25}{14}+\frac{33}{14}= \frac{58}{14} =2\frac{2}{14}=2\frac{1}{7}$
$2) 8-5\frac{7}{8}= \frac{8}{1}-\frac{47}{8} =\frac{64}{8}-\frac{47}{8} = \frac{17}{8}= 2\frac{1}{8}$
$3) 2\frac{1}{6} - 1\frac{1}{3} = \frac{13}{6} - \frac{4}{3} = \frac{13}{6}-\frac{8}{6}=\frac{5}{6}$
$4) 3\frac{1}{6}-2\frac{1}{12} =\frac{19}{6}-\frac{25}{12}=\frac{38}{12}-\frac{25}{12}=\frac{13}{12}= 1\frac{1}{12}$
