Question

Мастер за день сделал 42 детали, ученик 38 На сколько больше сделал мас., чем уч.за 7 дней?

Answer 1

1)42х7=294(детали)сделает мастер за 7 дней 2)38х7=266(деталей)сделает ученик за 7 дней 3)294-266=28(деталей) Ответ:на 28 деталей больше сделает мастер,чем ученик за 7 дней.  Можно ещё так решить:1)42-38=4(детали)делает больше мастер,чем ученик за один день 2)4х7=28(деталей)сделает больше мастер,чем ученик за 7 дней.

Answer 2

Calculation of Production Difference

To find out how many more parts the master made than the apprentice in 7 days, we can calculate the total production for each of them over 7 days.

The master made 42 parts in 1 day, so in 7 days, the master would make 42 * 7 = 294 parts.

The apprentice made 38 parts in 1 day, so in 7 days, the apprentice would make 38 * 7 = 266 parts.

Difference in Production

To find the difference in production between the master and the apprentice over 7 days, we subtract the total production of the apprentice from the total production of the master.

So, the master made 294 parts in 7 days, and the apprentice made 266 parts in 7 days.

Therefore, the master made 294 - 266 = 28 parts more than the apprentice in 7 days.

This means that the master made 28 more parts than the apprentice over the course of 7 days.
