Question

When rounding to the nearest hundred thousand, the weight of a blue whale was rounded to 500,000 pounds. What is the least the blue whale could actually weigh?

Answer 1

450,000 pounds

Explanation:

to round off to the nearest hundred thousand, look at thousand figure - If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

to be rounded off to 500,000, it means that the thousand figure has to be between 50,000 - 99,000

the least figure would thus be 450,000
