Answer:

The answer is

B. Compatible Numbers Strategy

Step-by-step explanation:

According to learnalberta "The compatible numbers strategy is a method of estimating computations by using "friendly" or "nice" numbers that can be easily calculated mentally. Compatible numbers can be used in estimating sums, differences, products and quotients."

So the closest number to 249 that can be divided by 12 is 240

240/12= 20
