Question

a 2 Marlene is thinking of a number. When the number is rounded to the nearest thousand, it is 3,000. When the number is rounded to the nearest hundred, it is 3,200. P O R 3.000 3,500 4.000 Which letter shows the location of Marlene's number on the number line?

Answer 1

The nearest thousand means "rounding of any decimal numbers to its nearest thousandth value."

Let's say that this number is x.

If we rounded x to the nearest thousand, it is 3,000.

So x>3,500

Then, if we rounded this number to the nearest hundred, which means "at the tens digit. If it is 5 or more, then round up. If it is 4 or less, then round down."

So x<3,250

Looking at the straight line, the correct location is P.
