Question

$x + \frac{4}{10} = \frac{7}{6}$
$x - \frac{5}{10} = \frac{5}{8} \\ \frac{4}{5} - x = \frac{3}{11}$
$x - \frac{2}{7} = \frac{5}{8} \\ x - \frac{3}{7} = \frac{4}{9}$

$\frac{5}{6} \: \: \: u\: \: \: \frac{3}{10} \\ 2 \frac{5}{12} \: \: u\: \: 2 \frac{3}{3}$
​

Answer 1

Ответ:

Пошаговое объяснение:

x + 4/10 = 7/6

x = 7/6 - 4/10

x = 35/30 - 12/30

x = 23/30

===========

x - 5/10 = 5/8

x = 5/8 + 1/2

x = 5/8 + 4/8

x = 9/8

x = 1 1/8

============

4/5 - x = 3/11

x = 4/5 - 3/11

x = 44/55 - 15/55

x = 29/55

==============

x - 2/7 = 5/8

x = 5/8 + 2/7

x = 35/56 + 16/56

x = 51/56

==============

x - 3/7 = 4/9

x = 4/9 + 3/7

x = 28/63 + 27/63

x = 55/63

=============

================

5/6 и 3/10

25/30 и 9/30

5/6 > 3/10

если это надо было сравнить

==============

2 5/12 и   2 3/3

2 2/12 и 3

2 5/12 < 2 3/3
