1) 196<13175>60
2) 164<5593,25>24
вроде так как то
1) 720 : 8 = 90 2) 80 - 7 = 73
90 * 8 = 720 73 + 7 = 80
720 : 90 = 8 80 - 73 = 7
8 * 90 = 720 7 + 73 = 80
А) (3 1/2х-1 5/14)×42=6
3 1/2х-1 5/14×42=6
3 1/2х-57=6
3 1/2х=6+57
3 1/2х=63
х=63:3 1/2
х=63:7/2
х=63×2/7
х=18
б) 8,2х+1 7/12=7 5/18
8,2х=7 5/18-1 7/12
8,2х=7 10/36-1 21/36
8,2х=6 46/36-1 21/36
8,2х=5 25/36
х=5 25/36:8,2
х=180/36:8 2/10
