Question

What fraction of these circles has X’s in them?

Answer 1

Hint: To obtain what fraction of circles has X’s in them we will divide the number of circles having the X’s in them with the total number of circles. Firstly we will count the circle with X’s in them and the total number of circles. Then we will divide the circle with X’s in them with the total number of circles given and simplify the obtained fraction to get our desired answer.

Complete step by step answer:
So from the figure given we can see that
Total number of circles $=8$
Circles with X’s $=4$
So the fraction of circles with X’s in them will be as follows:
Fraction of circle with X’s $=$ Number of circle with X’s $\div $ Total number of circles
Fraction of circle with X’s $=\dfrac{4}{8}$
Fraction of circle with X’s $=\dfrac{1}{2}$
Hence fraction of these circles has X’s in them is $\dfrac{1}{2}$

Note: Fraction is a numerical value that is a part of a whole. If we divide a number of things in equal parts then each part will be a fraction of the whole. The fraction is denoted as $\dfrac{x}{y}$ where $x$ is the numerator and $y$ is the denominator. We can write the fraction in decimal form as well. The numerator tells the part of the whole while the denominator is the whole whose fraction it is. The three types of fractions are Proper fractions, Improper fractions and mixed fractions. Real example of fraction is a pizza divided into six equal parts than each part is a fraction of $\dfrac{1}{6}$
