Answer 2

To simplify the expression, let's break it down step by step:

1. (-0.009:0.01): The division of -0.009 by 0.01 is the same as multiplying -0.009 by the reciprocal of 0.01, which is 100. So, (-0.009:0.01) equals -0.009 * 100 = -0.9.

2. (1/6 - 0.8 + 2/3): To simplify this expression, let's find a common denominator for 6 and 3, which is 6. Then, we have: (1/6 - 0.8 + 2/3) = (1/6 - 0.8*6/6 + 2/3) = (1/6 - 4.8/6 + 2/3) = (1 - 4.8 + 4)/6 = (-0.8)/6 = -0.1333...

3. -3целых6/25: This expression seems to have a mixed number in it. To convert it to a fraction, we multiply the whole number (-3) by the denominator (25) and add the numerator (6). Then, we place the result over the denominator. So, -3целых6/25 can be rewritten as (-3*25 + 6)/25 = (-75 + 6)/25 = -69/25.

4. (-1/4):(-0.02): Dividing a number by another number is the same as multiplying it by the reciprocal of the second number. Therefore, (-1/4):(-0.02) is equivalent to (-1/4) * (-1/0.02). Simplifying this expression, we have: (-1/4) * (-1/0.02) = (-1/4) * (-1/-0.02) = (-1/4) * (1/0.02) = (-1/4) * 50 = -50/4 = -12.5.

5. Putting it all together: (-0.9 : -0.1333...) : -69/25 + (-12.5) = (approx.) 6.7595 : -69/25 + (-12.5)

To evaluate this expression further, we need to clarify the order of operations. Are we supposed to calculate the division first, then addition, or are we supposed to calculate addition first, then division?
