Answer 1

1)-0,78*(-0,19)=0,1482
2)-0,22*0,19=-0,0418
3)0,1482-0,0418=0,1064
___________________

1/2=0,5
4)3,6*0,5=1,8
5)1,8:0,018=100
6)0.1064/100=0,001064

Answer 2

Let's solve the expression step by step:

Step 1: Calculate the first part of the expression -0.78 * (-0.19) - 0.22 * (0.19)

To perform the multiplication, we get: 0.1482 - 0.0418

Now, subtract the two values: 0.1064

Step 2: Calculate the second part of the expression 3.6 * 1/2 ÷ 0.018

To begin, perform the division: 3.6 * 1/2 = 1.8

Now, divide 1.8 by 0.018: 1.8 ÷ 0.018 = 100

Step 3: Final calculation Now, we have: 0.1064 ÷ 100

Divide 0.1064 by 100: 0.1064 ÷ 100 = 0.001064

So, the final result of the expression is 0.001064.
