решите . за и за то что рано.Народ очень надо даю.Это математика 6 класс.Заранее .​

Answer 1

1)

$0.8(3.7 - 6.3) = 0.8 \times - 2.6 = - 2.08$

2)

$1.2 \times 3.6 + 5.78 = 4.32 + 5.78 = 10.1$

3)

$2.1 \times 2.7 + 6.43 = 5.67 + 6.43 = 12.1$

4)

$(3.7 - 5.9) \div 0.4 = - 2.2 \div 4 = - 0.55$

5)

$(3.7 - 5.2) \times 0.8 = - 1.5 \times 0.8 = - 1.2$

6)

$- 7.1 + 7.68 \div 1.2 = - 7.1 + 6.4 = - 0.7$

7)

$- 8.8 + 6.5 \times 1.6 = - 8.8 + 10.4 = 1.6$

8)

$(2.3 - 5.9) \div 40 = - 3.6 \div 40 = - 0.09$

9)

$(4.2 - 6.6) \div 60 = - 2.4 \div 60 = - 0.04$

10)

$- 7.5 + 15.3 \div 1.5 = - 7.5 + 10.2 = 2.7$

11)

$- 9.7 + 18.9 \div 1.4 = - 9.7 + 13.5 = 3.8$
