Answer:-0.027
Explanation:
We keep all of the numbers that's why there's still the 2 and 7 and it's negative, then we move the decimal point left 2 times because that is the power of 10.
When the number next to the 10 is positive, we would move the decimal point to the right, when it is negative like it is here (-2), it is moved to the left. I hope that helps!
