solve the following problems using pictures, number or words.
At president's inaguration in 2005, the newpaper headlines stated there were about 400,000 people in attendance. If the newpaper rounded to the nearest ten thousand, what is the largest number and smallest number of people who could have been there
I answered the last problem for you. Now it's your turn.
What do you think?
what about low as 395,000 and as high as 404,999
To solve this problem, we need to understand the concept of rounding to the nearest ten thousand.
Rounding means approximating a number to the nearest specified place value, in this case, the nearest ten thousand. To round a number to the nearest ten thousand, we look at the digit just to the right of the ten thousand place.
If this digit is 5 or greater, we round the number up to the next ten thousand. If the digit is less than 5, we round the number down to the current ten thousand.
In the case of the newspaper headline stating there were about 400,000 people in attendance, the number 400,000 is already rounded to the nearest ten thousand.
To find the largest and smallest number of people who could have been there, we need to consider the possible rounding scenarios:
1. Largest Number: If the number is already rounded up, meaning the digit to the right of the ten thousand place is 5 or greater, we keep the number as it is. In this case, the largest number of people who could have been there would be the same as the rounded number, which is 400,000.
2. Smallest Number: If the number is already rounded down, meaning the digit to the right of the ten thousand place is less than 5, we need to subtract 10,000 from the rounded number to find the smallest number. In this case, the smallest number of people who could have been there would be 390,000.
Therefore, the largest number of people who could have been there is 400,000 and the smallest number is 390,000.
