Пошаговое объяснение:

Масштаб 4:1 - увеличение, следовательно, 60:4 = 15 см - реальная длина детали

Масштаб 1:3 - уменьшение, следовательно, на чертеже длина детали = 15:3 = 5 см

I had a light meal and gave my son some money for his school lunch. “Can I have some money for an ice-cream, too, Daddy” he asked. “Don’t ask silly questions”, I said angrily. “Why did I say that?” I thought as I drove to the office, I went through the red light, and a policeman stopped and fined me.
