Answer:

With the way the problem is facing, the correct option is B.

  • Round the decimals to their nearest whole.


6.2
6


9.55
10

  • We know that 6 - 10 is 4, so our estimate will be close to 4. The next step is to subtract the rounded numbers.


6 - 10 = -4 because of the order. Otherwise, it would be positive 4

  • Now, we must pick the answer that would be close yet far to our estimate. Hmm, if 0.55 + 0.2 is 0.75, while subtracting, that would be different. It would be a bigger decimal, because normally, when the number decreases, the decimal may increase slightly. With that information, 3.35 sounds close to what we are looking for, so let's pick that.


6.2 - 9.55 = -3.35

And the problem is solved. -3.35 is your answer. Remember, in the future, always go by the order of operations. If you do not follow the order of operations, that could be a disaster!
