Question

Знайдіть значення виразу
1/3+1/4-5/12
²2/3+6/7-¹29/21

Answer 1

Ответ:

$\frac{1}{3} + \frac{1}{4} - \frac{5}{12} = \frac{4 + 3 - 5}{12} = \frac{2}{12}$

Answer 2

Ответ:

1) 1/3+1/4-5/12

$\frac{1}{3}+\frac{1}{4} -\frac{5}{12}=\frac{4+3-5}{12} =\frac{2}{12}=\frac{1}{6}$

2) ²2/3+6/7-¹29/21

$2\frac{2}{3}+\frac{6}{7} -1\frac{29}{21} =\frac{3*2+2}{3} +\frac{6}{7}-\frac{21*1+29}{21} =\frac{8}{3} +\frac{6}{7}-\frac{50}{21}=\frac{56+18-50}{21} =\frac{24}{21}=\frac{8}{7}=1\frac{1}{7}$
