? Building on the Essential Question How can I show how numbers are related to each other?
Answer:
You can show the relation of both numbers by simply identifying the place value of each digit.
For example, the number is 555.55
First 5 in the left has the value of a hundred, followed by tens and ones.
Then the number next to the decimal point has a value of tenths and the next is hundredths.
Now, how the find the relationship of the given number
