Question

Estimate the addition by rounding each number to the nearest hundred thousand. Then find the sum. Estimate: 229,275 +115,368 344633​

Answer 1

600,000

Explanation:

When rounding to the nearest 100,000 if it's X50,000 you round up 1 for the X, if it's X49,999 or less you keep the X as is.

229,275 rounding to the hundred thousand would be 200,000

115,368 would be 100,000

344,633 would be 300,000

so 200,000+100,000+300,000 = 600,000
