Which number is to the right of 1.78 on a number line

2

Step-by-step explanation:

The next whole number is 2, but if you're counting by 0.01's the answer is 1.79.

Step by step explanation:

On a number line, the numbers to the right are one unit greater than the number on its left. The number on the right of 1.78 depends on what the number line is counting by- if the number line is counting by hundredths (0.01's), the number on the right would be 1.79. If the number 1.78 is labeled on the number line, the number line is most likely not counting by whole numbers because 1.78 is not a whole number. There are infinitely more units to count by- 0.001's, by 5's, and so on.
