A. 300-200=100
You round 267 to 300, 154 to 200, and 113 to 100.

A, C and D are all using estimation to check the result. 

A is rounding to the nearest multiple of 100. 
267 --> 300 
154 --> 200 <span>

C is rounding to the nearest multiple of 50. </span>
<span>267 --> 300 </span>
<span>154 --> 150 </span>

<span>D is rounding to the nearest multiple of 10. </span>
<span>267 --> 270 </span>
<span>154 --> 150 </span>

<span>Those each give you an estimation of the final answer to see if 113 is a reasonable answer. </span>

<span>Method B is just switching the values around to check the subtraction using addition. That's a valid way to double check the result, but is NOT estimation. </span>

<span>If you are only expected to give *one* answer, then method D is the best way to check using estimation because it does the least amount of rounding. </span>

<span>Answer: </span>
D. 270 - 150 = 120
