B) 100,000.The nearest ten thousand estimate for 104,297 is 100,000, which makes option B) 100,000 the correct answer.
Step-by-step explanation:
The correct answer is option B) 100,000. When estimating the sum or nearest ten thousand for the number 104,297, one should look at the thousands place. The number lies between 100,000 and 110,000. Since 104,297 is closer to 100,000 than to 110,000 (the thousands digit '4' is less than '5'), it should be rounded down to 100,000.
Estimation is a valuable skill in mathematics that provides a quick and simple way to approximate the value of a number based on its position relative to certain significant figures, like ten thousand in this case.
To estimate the sum of 10,000 and 104,297, round each number to the nearest thousand. 10,000 rounds to 10,000 and 104,297 rounds to 100,000. Add these two rounded numbers together to get an approximate sum of 110,000. Since none of the answer choices match exactly, the closest option is B) 100,000.
