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
