Answer 1

111.548

-------------------------------

Subtract 201 from 89.

`201 - 89 = 112`

we can estimate the answer will be close to 112

Next, work with the decimals. Note that the more you subtract, the bigger the decimal places get.

`0.768 - 0.316 = 0.452`

Round 0.452 up from the hundredths place to nearest tenths place.

`0.452 = 0.5`

Since the decimal place is bigger, estimate 0.55 instead.

Subtract 0.22

`0.55 - 0.2 = 0.548`

Add this number to 112

`112 + 0.548 = 112.548`

Subtract 1 because of the estimate.

`112 - 1 = 111`

Therefore, we have 111.548 based off of subtracting and estimating in a specific method.
