solve the following problems using pictures, number or words.
At president's inaguration in 2013, the newpaper headlines stated there were about 800,000 people in attendance. If the newpaper rounded to the nearest hundred thousand, what is the largest number and smallest number of people who could have been there
750,000
849,000
In the 2011new York city marathon 29,867 men finished the race and16,928
900,000
To solve this problem, we can use the concept of rounding to the nearest hundred thousand. Rounding means approximating a number to the nearest specified place value. In this case, we are rounding to the nearest hundred thousand.
To find the largest number of people who could have attended the inauguration, we need to round up to the nearest hundred thousand. We can visualize this by picturing a number line with intervals of 100,000. Starting from 800,000, we move to the next interval. Since the next interval is larger than 800,000, we round up to the nearest hundred thousand. Therefore, the largest number of people who could have attended is 900,000.
To find the smallest number of people who could have attended, we need to round down to the nearest hundred thousand. Again, picturing a number line, we move to the previous interval from 800,000. Since this interval is smaller than 800,000, we round down. Therefore, the smallest number of people who could have attended is 800,000.
In summary:
- Largest number: 900,000
- Smallest number: 800,000
