Answer 2

1) (-1/2 + 2/3) * 0.36 - 2 + 2 First, we need to add the fractions -1/2 and 2/3. To do this, we need to find a common denominator, which is 6. So, -1/2 becomes -3/6 and 2/3 becomes 4/6. Adding these together gives us 1/6.

Next, we multiply 1/6 by 0.36, which equals 0.06.

Now we can simplify the expression: 0.06 - 2 + 2 = 0.06.

2) 3/4 : 5/6 + 2 + 1/2 + 2/3 - 1 : 1 + 1/9 First, we need to divide 3/4 by 5/6. To do this, we multiply 3/4 by the reciprocal of 5/6, which is 6/5. This gives us (3/4) * (6/5) = 18/20 = 9/10.

Next, we add 9/10 to 2, which gives us 2.9.

Now we add 1/2 to 2.9, which gives us 3.4.

Next, we add 2/3 to 3.4, which gives us 4.

Finally, we need to divide 1 by 1 and add 1/9. 1 divided by 1 is 1, and adding 1/9 gives us 1.1111.

So, the final answer is 4 + 1.1111 = 5.1111.
