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 .

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 will write 32 as a fraction.  We know that whole numbers can be written as a fraction over 1.  So,

Now, we will multiply straight across.  We get

Therefore,   of  is .

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 will write 72 as a fraction.  We know that a whole number can be written as a fraction over 1.  So,

Now, we will multiply straight across.  We get

Therefore,   of  is .

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

half of 28

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

 of 

Now, we can multiply.  We get

To multiply, we need to write 28 as a fraction.  We know we can write whole numbers as fractions over 1.  So, we get

Now, we can multiply straight across.  We get

Therefore, half of 28 is 14.

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

Let's look at the problem.

half of 12

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

 of 

Now, we will multiply them together.  So, we write

To multiply, we will write 12 as a fraction.  We know that whole numbers can be written as fractions over 1.  So, we get

Now, we will multiply straight across.  We get

Therefore, half of 12 is 6.

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

 of 

we will write it like

Now, to multiply, we will write 27 as a fraction.  We know that whole numbers can be written as fractions over 1.  So, 

Now, we will multiply straight across.  We get

Therefore,  of  is .

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 like this:

Now, we will write 32 as a fraction.  We know that whole numbers can be written as fractions over 1.  So, we get

Now, we can multiply straight across.  We get

Therefore,   of  is .

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

So, in the problem

 of 

we can re-write it as

Now, to multiply, we will write 24 as a fraction.  We know that a whole number can be written as a fraction over 1.  So, we get

Now, we can multiply straight across.  We get

Therefore,   of  is .

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

So, in the problem

 of 

we can re-write it as

Now, to multiply, we will write 63 as a fraction.  We know that whole numbers can be written as fractions over 1.  So, we get

Now, we can simplify before we multiply to make things easier.  The 7 and the 63 can both be divided by 7.  So, we get

Now, we can multiply straight across.  We get

Therefore,   of  is .

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 like this:

Now, we must write 75 as a fraction.  We know that a whole number can be written as a fraction over 1.  So, we get

Now, we can multiply straight across.  We get

Therefore,  of  is .
