Explanation:

When looking at the problem, we see we need to find a quarter of .  The first thing we need to do is write "a quarter" in fraction form.

We know that a quarter is the same as .  So, we can write it like

of

Now, to find a fraction of a whole number, we will multiply the fraction by the whole number.  We get

Now, to multiply, we will write  in fraction form.  We get

Now, we can multiply straight across.  We get

Therefore, a quarter of  is .

### Example Question #142 : Numbers And Operations

Find  of .

Explanation:

To find a fraction of a whole, we will multiply the fraction by the whole number.  So,

of

can be written as

Now, to multiply, we need to write 36 as a fraction.  We know that any whole number can be written as a fraction over 1.  So, we get

Now, we will multiply straight across.  We get

Therefore,   of  is .

### Example Question #143 : Numbers And Operations

Find  of .

Explanation:

To find a fraction of a whole number, we will multiply the fraction by the whole number.

So,

of

can be written as

Now, to multiply, we need to write 16 as a fraction.  We know we can write any whole number over 1.  So, we can write 16 over 1.  We get

Now, we can multiply straight across.  We get

Therefore,   of  is .

### Example Question #144 : Numbers And Operations

Find three-quarters of .

Explanation:

To find a fraction of a whole number, we will multiply the fraction by the whole number.

So, in the problem

three-quarters of

we will first write three-quarters as a fraction.

Three-quarters is the same as .  So, we can write it as

of

which can be re-written as

Now, we need to write 12 as a fraction.  We know that whole numbers can be written as the number over 1.  So, we can write it as

Now, we can multiply straight across.  We get

Therefore, three-quarters of  is .

### Example Question #31 : How To Find The Part From The Whole

What is  of  ?

Explanation:

To find a fraction of a whole number, we will multiply the fraction by the whole number.

So, in the problem

of

we can write it as

Now, we will write 27 as a fraction.  We know a whole number can be written as a fraction over 1.  So,

Now, before we multiply, we can simplify to make things easier. We know that 3 and 27 can both be divided by 3.  So,

Now, we can multiply straight across.  We get

Therefore,  of  is .

### Example Question #151 : Isee Lower Level (Grades 5 6) Mathematics Achievement

What is half of  ?

Explanation:

To find a fraction of a whole number, we will multiply the fraction by the whole number.

So, in the problem

half of

we will first write half as a fraction.  We know that half can be written as .  So, we can write it as

Now, we will write 14 as a fraction.  We know whole numbers can be written as a number over 1.  So, we get

Now, we will multiply.  We get

Therefore, half of  is .

### Example Question #152 : Isee Lower Level (Grades 5 6) Mathematics Achievement
