Using a number line, what whole number and rational numbers the nearest half is 20 between?

Answer 1

To determine the whole number and rational numbers that the nearest half is 20 between, we can start by finding the integer that is closest to but less than 20. On a number line, we see that 19 is the integer that is closest to but less than 20.

Next, we find the next whole number that is closest to but greater than 20. Again, on the number line, we see that 20 is the whole number that is closest to but greater than 20.

Now, we need to find the rational numbers that are exactly halfway between these two whole numbers.

For the rational number that is halfway between 19 and 20, we can add 0.5 to the lesser whole number:

19 + 0.5 = 19.5

For the rational number that is halfway between 20 and 21, we can add 0.5 to the higher whole number:

20 + 0.5 = 20.5

Therefore, the whole number and rational numbers the nearest half is 20 between are:

19, 19.5, 20, and 20.5.
