2.94÷0.6 = 2.940.6 = 29460 = 49 · 610 · 6 = 4910 = 4·10 + 910 = 4910 = 4.9
42÷0.75 = 420.75 = 420075 = 56 · 7575 = 56 = 56
3÷75 = 375 = 1 · 325 · 3 = 125 = 0.04
28÷0.35 = 280.35 = 280035 = 80 · 3535 = 80 = 80
4910 + 56 = 4 + 910 + 56 = 60 + 910 = 60910 = 60.9
60910 - 125 = 9 + 60·1010 - 125 = 60910 - 125 = 609·510·5 - 1·225·2 = 304550 - 250 = 3045 - 250 = 304350 = 60·50 + 4350 = 604350 = 60.86
