Szczegółowe wyjaśnienie:
4,6 * 1 1/9 - (1,2)² + 6,25 : 5/8 = 46/10 * 10/9 - (12/10)² + 625/100 : 5/8 =
414/100 - 144/100 + 6250/1000 : 625/1000 = (414 - 144)/100 + 6250/1000 * 1000/625 = 270/100 + 6250/625 = 2,7 + 10 = 12,7
3 1/7 * 2,1 - (2/3)² + 7,4 : 37/40 = 22/7 * 21/10 - 4/9 + 74/10 : 37/40 =
33/5 - 4/9 + 74/10 * 40/37 = 297/45 - 20/45 + 80/10 = 277/45 + 8 =
6 7/45 + 8 = [tex]14\frac{7}{45}[/tex]
