Answer 1

Ответ:

1)-3,4

2)-0,9

3)-1,6

4)1,5

Answer 2

Let's solve these arithmetic expressions step by step:

1. -5.2 + 1.8: -5.2 + 1.8 = -3.4

2. -2.3 - (-1.4): To subtract a negative number, you can change it to addition. So, -2.3 - (-1.4) becomes -2.3 + 1.4: -2.3 + 1.4 = -0.9

3. 3.2 × (-0.5): 3.2 multiplied by -0.5 is: 3.2 × (-0.5) = -1.6

4. -2.25 ÷ (-1.5): To divide by a negative number, you can change it to multiplication by the reciprocal. So, -2.25 ÷ (-1.5) becomes -2.25 × (-2/3): -2.25 × (-2/3) = 1.5

So, the answers to the expressions are:

1. -5.2 + 1.8 = -3.4
2. -2.3 - (-1.4) = -0.9
3. 3.2 × (-0.5) = -1.6
4. -2.25 ÷ (-1.5) = 1.5
