Answer 1

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`
