Final answer:
To evaluate the expression 0.9÷(−0.8÷(−1−0.7)), we follow the order of operations and obtain 1.914893…
Step-by-step explanation:
To evaluate the expression 0.9÷(−0.8÷(−1−0.7)), we need to follow the order of operations: parentheses, then division. Let's start with the innermost parentheses:
−1−0.7 = -1 - 0.7 = -1.7
Now, we can evaluate −0.8÷(−1−0.7) by dividing -0.8 by -1.7:
−0.8÷(−1−0.7) = -0.8 ÷ -1.7 = 0.470588…
Finally, we can evaluate 0.9 divided by the result from the previous step:
0.9÷(−0.8÷(−1−0.7)) = 0.9 ÷ 0.470588… = 1.914893…
Therefore, the answer is approximately 1.914893… which should not be rounded.
