How many fractions are there between any two numbers on a number line?

50

20

100

an infinite number

There are an infinite number of fractions in between numbers on a number line.

Step-by-step explanation:

The reason for this is because we have an infinite number of denominators to use. Therefore, we can not number the amount we use.

An infinite number.

Step-by-step explanation:

We have to find number of fractions between two numbers on a number line. Basically fractions are rational numbers. So, if we found the number of rational numbers between two numbers on a number line we are done. We can find infinite number of rational numbers between two number on a number line. It depends on us as to how we want to divide or the number of fractions we want. If we want we can divide an interval into 50 fractions, 100 fractions and so on but there are infinite numbers we can choose from.
