First, you draw a number line. You then make points for the counting numbers, and place the mixed numbers and decimals between these points, getting their own points and labels.
your dumb if you don't know how to round decimals on a number line
The question cannot be answered because there are an infinite number of decimals between any two points!
If we are talking whole numbers, then 9 is between 8 and 10. But if you have a number line measure in tenths (decimals), then 9 is between 8.9 and 9.1. If the number line is in halves, then 9 coms in between 8 and a half and 9 and a half. There are lots of answers. It just depends on the scale of the number line.
No
There are infinitely many fractions and decimals between 0 and 1.
The decimals between 0.3 and 0.35 are 0.31, 0.32, 0.33, and 0.34. These numbers fall sequentially between 0.3 and 0.35 on the number line. Each of these decimals represents a fraction of a whole between 0.3 and 0.35.
You see which tick is nearer to the point on the number line.
fractions are represented in form of decimals
Adding and subtracting decimals is easy. When you put the numbers one above the other, line up the decimals vertically and treat as you would any whole number just keep the decimals in line and bring it straight down to your answer.
First, you calculate it to the desired number of decimals. Then you place it on the number line in the usual manner.
The line between the numerator and the denominator of a fraction is the the solidus line
