1.6 Вычислите: a) 42: 7.8; 60.5:10; 630:9.3; 6) 72: 8.3; 44:42; 360: 4:3; в) 12.3:9; 46:2.3; 280: 4:7; г) (37 + 11) (53 - 39) 49: (71

a) 42 : 7 * 8 = 6 * 8 = 48

60 * 5 : 10 = 300 : 10 = 30

630 : 9 * 3 = 70 * 3 = 210

б) 72 : 8 * 3 = 9 * 3 = 27

44 : 4 * 2 = 11 * 2 = 22

360 : 4 : 3 = 90 : 3 = 30

в) 12 * 3 : 9 = 36 : 9 = 4

46 : 2 * 3 = 23 * 3 = 69

280 : 4 * 7 = 70 * 7 = 490

г) (37 + 11) = 48

(53 - 39) = 14

49 : (7 + 1) = 49 : 8 = 6.125
