Estimate the sum to the nearest tens place

150+121+141+149=

15 + 15 = 30

12 + 14 = 16
Total = about 40

Ms. Sue can you explain this. I Don't where the two 15's come from

Please forget my last post. I think aliens temporarily kidnapped my brain!

I didn't complete the problem. (Good heavens, I didn't even add right!) I should have added the zeros back in.

150 + 150 + 120 + 140 = 560

To estimate the sum to the nearest tens place, you can round each of the given numbers to the nearest tens place, then add them together.

Let's round each number to the nearest tens:

150 rounds to 150
121 rounds to 120
141 rounds to 140
149 rounds to 150

Now, add these rounded numbers together:

150 + 120 + 140 + 150 = 560

Therefore, the estimated sum to the nearest tens place for the given numbers is 560.
