один из вариантов:

смешанную дробь сделать неправильной, для этого целую часть умножить на знаменатель от дробной части и прибавить числитель, а в знаменателе оставить знаменатель от дробного числа.

обычное число представить в виде числа разделить на единицу (напр., 6 в 6/1)

и потом проводить манипуляции с умножением.

Смешанное число 2 3/7 надо при умножении перевести в неправильную дробь.

2 3/7 * 3=(7*2+3)/7 * 3=17/7 * 3=(17*3)/7=

51/7=7 2/7 - это ответ.
