On Monday, the people on Lou's boat caught 284 fish. On Tuesday, they caught 421 fish, and on Wednesday they caught 198 fish. if you are estimating by rounding to the nearest hundred, what number should you use to estimate the total number of fish caught during those three days?
I would approach the problem by first adding all the numbers together. The three total 1,003 if added correctly. If being rounded to the nearest hundred, 1,003 would round down to 1,000. Therefore, the number that should be used is 1,000.
