What is the estimated quotient if 255.1/8

Best estimate is 32.

Step-by-step explanation:

Note that 8 divides evenly into 240, and that this quotient comes out to

240/8, or 30. Thus, the estimated quotient 255.1/8 is approx. 30, which is smaller than the actual quotient.

We could stop here, or we could experiment, as follows:

Since 240/8 = 30, 248/8 = 31, and 256/8 = 32.

Note that 248 comes from adding 8 to 240 and that 256 comes from adding 8 to 248.

32 is the best estimate of 30, 31 and 32.
