Solve the equation. Show or explain your work.
Compared to your estimate, is your answer reasonable? Explain your answer in complete sentences.

ANSWER 1: The estimate for 2.15 is 2. (If you are rounding to the ones.)

ANSWER 2: The estimate for 2.15 is 2.2. (If you are rounding to the tenths.)

Step-by-step explanation:

ANSWER 1: I know this because the one in 2.15 is lower than 5 so the 2 would stay the same. Then the 5 and 1 would turn to a 0.

ANSWER 2: I know this because the 5 in 2.15 is higher than 4 so the 1 would turn to a higher number which would be 2.

Hopefully I explained it well and I did it right because I haven’t rounded decimals in a while.

So sorry if I did it wrong.
