5 600 - 4 900 ÷ ( 70 - 4 × 15 ) + + 85 = 5195
1) 4 × 15 = 60
2) 70 - 60 = 10
3) 4 900 ÷ 10 = 490
4) 5600 - 490 = 5 110
5) 5 110 + 85 = 5 195
(68 + 32 ÷ 4) - (12 × 5 - 3) =
= 9
1) 32 ÷ 4 = 8
2) 68 + 8 = 76
3) 12 × 5 = 60
4) 60 - 3 = 57
5) 76 - 57 = 9
Пошаговое объяснение:
1) 5600-4900:(70-4*15)+85=5600-4900:(70-60)+85=5600-4900:10+85=5600-490+85=5110+85=5195
1)4*15=60
2)70-60=10
3)4900:10=490
4)5600-490=5110
5)5110+85=5195
2) (68+32:4)-(12*5-3)=(68+8)-(60-3)=76-57=19
1)32:4=8
2)68+8=76
3)12*5=68
4)68-3=57
5)76-57=19
