Пошаговое объяснение:

сначала перевели вторую дробь в неправильную

3/10× 2 2/9=3/10×20/9

дальше можно сократить 3 и 9 ; 10 и 20. тогда у нас остаётся

1/1×2/3=2/3

на этом и все

ivankabachok: 9 и 3 надо сократить на 3

ivankabachok: А 20 и 10 на 5

Cuutee: да

Cuutee: было лень писать, соре

kris7398: Спасибо
