• why would we need them in a line
• Hi, Edwin!

Just like how you count 1 to 2 to 3 to 4, we are also increasing our values as we go right and decrease them as we go down.

The number line is to help us evaluate the location of a number or fraction on a scale. it is also a pointer that if we add, subtract, multiple, or divide said numbers into each other, where they would end up or be on said number line.

It's not crucial to use a number line in order to do these problems. the number line is mostly a visual representation and a helpful reminder for people who have trouble spotting where their numbers should be.

Thank you so much for the question! have a nice day! :)

• You would have your starting number, and then you would have fractions like 1/8, 1/4 etc. and go up to you ending number.
• There are actually infinitely many numbers in between those two numbers. There are infinitely many numbers in between any two numbers. However, what I think you're looking for is: `5.11, 5.12, 5.13, 5.14, 5.15, 5.16, 5.17, 5.18, 5.19`
