What fractions of these circles have X's in them?

The number of circles having X divided by the total number of circles will give the required fraction.

Answer: The fraction of these circles having X's in them is 1/2.

Let's understand these questions step by step.

Explanation:

We see that there are 8  circles, out of which 4 have X marked in them

the total number of circles = 8

Total number of circles having X = 4

Therefore, required fraction = number of circles with X / total number of circle  = 4/8

= 1/2.

Thus, the fractions of these circles having X's in them is 1/2.
