Final answer:
Rounding is not a good strategy when estimating division because it can lead to inaccurate results.
Step-by-step explanation:
Rounding is not a good strategy when estimating 1320 divided by 6 because it can lead to inaccurate results. When we round, we lose some of the precision of the numbers involved. In this case, if we round 1320 to the nearest 1000 and 6 to the nearest 10, we would get 1000 divided by 10, which is 100. However, the actual answer is 220. Rounding can introduce significant errors in calculations, especially when dealing with larger numbers or when precision is important.
