Match the fraction to the appropriate drawing or part of a set

Did You Know?

Fractions are used to name equal parts of a whole or group.  For example, these fraction bars
show how a whole can be divided into sixths, or six equal parts.

Check What You Know First

Parts of a Whole


Write down how many parts are shaded.  Then write how many equal parts make up the whole figure.  Then check the answer.

Parts of a Group

Write how many groups are circled.

Then write how many total groups there are.

 

Key Vocabulary to Know 

A fraction is a number that names part of a whole or part of a set.

The numerator tells how many parts are being counted. 

It is the top number in a fraction.

The denominator tells how many equal parts are in the whole. 
Think of it as how many parts you can count in all. 

 

It is the bottom number in a fraction.

Try a Fraction Problem

six

Which object would be equivalent to 6/8?   

Learn About It Now

Let’s look at the fraction problem you did.  First look for the denominator of the fraction. 
The denominator is the total number of equal parts the fraction contains. You count how
many total parts in each figure.  In this problem the denominator is 8.  It is the bottom
number in the fraction 6/8. There are 3 answers that have 8 parts.  They are A, D and E.

80f8

Notice that D has eight total parts but they are unequal so this answer would be incorrect. 
A fraction must contain equal parts. We still have two letters that have 8 parts.  They are A and E.

8of8b

Now look for the numerator.  The numerator tells how many parts are being counted in the problem. 
In this problem, count how many shaded parts there are.  In this problem the numerator is 6. 
It is the top number in the fraction 6/8.  That makes the answer E.

8of8c

When we write fractions, we write the numerator on the top. 
We then draw a line or bar under the numerator.  The denominator is written underneath the line. 
Example:   6/8

The numerator is 6.

 

The denominator is 8.

tao

five

When we write the words for a fraction, the numerator name is pronounced the same as the number. 
However, the pronunciation of the denominator changes.  Look at some examples.

½ is one half, 1/3 is one third, ¼ is one fourth, 1/5 is one fifth, 1/6 is one sixth,
1/7 is one seventh, 1/8 is one eighth, 1/9 is one ninth, 9/10 is nine tenths, 3/12 is three twelfths

Also a fraction can be written in several other ways.  Look at these examples.

4/9 can be written 4 out of nine  or four ninths
2/3 can be written two divided by three or two thirds

When the numerator and denominator are the same number such as 6/6 that means
that six equal parts that are all counted equal one whole so 6/6 =1 whole
