Question

982,510 books were downloaded in one year. Round this number to the nearest hundred thousand to estimate how many books were downloaded in one year. Use a numberline to show your work

Answer 1

1,000,000.

Explanation:

You are rounding to the nearest hundred thousand place value, which will be underlined and bolded:

982,510

Note that when you round, you look at the digit directly next to the place value you are solving for. Note:

If the value of the digit is 5 or greater, round up.

If the value of the digit is 4 or less, round down.

In this case, the value directly next to the place value is the ten thousands place, which has the value of 8. Because 8 is greater than 5, you will round up.

982510 rounded to the nearest hundred thousand is 1,000,000.

For the numberline, simply plot the points on both end of the spectrum, with 0 being on the left and x value on the right. Plot 1,000,000 corresponding to the value given on the right.
