При пайке изделий из жести применяют сплав, содержащий 2 части свинца и 5 частей олова. Сколько свинца и олова содержит кусок сплава, в котором олова на 360 г больше, чем свинца?

Решите эту задачу по плану:

1) Сколько частей составляют 360 г?

2) Сколько граммов приходится на 1 часть?

3) Сколько свинца в сплаве?

4) Сколько олова в сплаве?

Решение 2. №249 (с. 78)

1) Сколько частей составляют 360 г?

Согласно условию, сплав содержит 5 частей олова и 2 части свинца. Чтобы найти, на сколько частей олова больше, чем свинца, нужно из количества частей олова вычесть количество частей свинца: $5 - 2 = 3$ части. По условию задачи, эта разница в 3 части соответствует 360 г.
Ответ: 360 г составляют 3 части.

2) Сколько граммов приходится на 1 часть?

Мы знаем, что 3 части составляют 360 г. Чтобы найти массу одной части, нужно общую разницу в массе разделить на разницу в частях: $360 / 3 = 120$ г.
Ответ: на 1 часть приходится 120 граммов.

3) Сколько свинца в сплаве?

В сплаве содержится 2 части свинца. Чтобы найти массу свинца, нужно количество его частей умножить на массу одной части: $2 \times 120 = 240$ г.
Ответ: в сплаве 240 г свинца.

4) Сколько олова в сплаве?

В сплаве содержится 5 частей олова. Чтобы найти массу олова, нужно количество его частей умножить на массу одной части: $5 \times 120 = 600$ г. Можно также проверить, что разница между массой олова и свинца равна 360 г: $600 - 240 = 360$ г.
Ответ: в сплаве 600 г олова.
