Is it reasonable to say the sum of 146 and 149 is less than 300? Explain.

Answer 1

I would say so because 146 rounds to 100 because you have to round to the greatest place value. 149 rouds to 100 as well. 100 + 100 is 200. I would say the sum would be less than 300.

Answer 2

Yes, it's reasonable.

300 / 2 = 150
