12 cm 2 mm = 12.2 cm 12.2*5 = 61 cm - piece length. 450*8 = 3600 g = 3 kg 600 g1) 12.2×5=61 (cm) - length of all piece (I am the 12th cm of 2 mm of Privratil in decimal fraction 12.2. we have to increase the 5th part by 12.2 to learn the exact length of this piece) 2) (I know as it is possible to make easily. let's present that the example looks so x: 450=8. I know for sure that to find a dividend it is necessary a divider × private and we will find a dividend. In this task in the same way) 450×8=3600(g) - the mass of all cargo
