правило сложения дробей с одинаковыми знаменателями
Нужно числители этих дробей сложить, а знаменатель оставить прежним. Если дробь сократимая, то ее сократить!
Примеры: 105 + 103= 105+3=108 = 54
Если дробь получилась неправильная, то выдели целую часть.
3310+3326=3336=1333=1111

правило вычитания дробей с одинаковыми знаменателями
Нужно числители этих дробей вычесть, а знаменатель оставить прежним. Если дробь сократимая, то ее сократить!
Пример: 105 - 103= 105−3=102 = 51
10051− 10026=10025=41
