Пошаговое объяснение:

180*0,1=18га убрали за 1 день

3(18+3)=63га убрали за следующие три дня

180-18-63=99га убрали за 4 дня

99/100*180=55% убрали за 4 дня

100%-55%=45% осталось убрать комбайнеру

Well, nine out of ten of them receive these hi-tech goods Christmas or birthday presents, while others save their pocket money or earn the money through working. Some parents might be shocked to find out that their son or daughter could be sleeping on a gold mine. It seems fair to say that as new technology increases so does the value of kids' bedrooms!
