В общем,1дм=10см,но взяла за 1 дм(единичный отрезок) 10 клеток.Так что у нас 1 клетка=1 см(образно). 0,25=1/4,т.е это половина половины от единичного отрезка.(точка будет лежать на 2,5 клетках от начала 0).0,05дм=1/2см,т.е половина клетки от начала 0.Дальше, 0,9дм=9 см(у нас девять клеток),точка будет лежать на клетку левее от единичного отрезка (1дм).0,37дм=3,7см(три елых клетки и 7 мм).0,73дм=7,3см(семь клеток и 3 мм).1,24дм=124 см (т.е это единичный отрезок плюс еще две елых клетки и 4 мм).Как-то так)
25*125*4*8=(25*4)*(125*8)=100*1000=100000
