1. Вычислим сколько часов работали рабочие, если известно, что один работал 3 часа, а другой 4 часа.

3 + 4 = 7 часов.

2. Найдем количество деталей, которые рабочие делали за один час.

56 / 7 = 8 деталей.

3. Узнаем сколько деталей сделал рабочий, который работал 3 часа.

3 * 8 = 24 детали.

4. Определим сколько деталей сделал второй рабочий, если известно, что он работал 4 часа.

4 * 8 = 32 детали.

Ответ: Первый рабочий изготовил 24 детали, а второй рабочий изготовил 32 детали.

airport and they drove to the south of Moscow where the
Smirnovs lived. In Moscow John and Sally stayed with the
Smirnovs but in St Petersburg they had a room in a small
hotel. John and Sally loved Moscow and they enjoyed
St Petersburg very much.Unit
