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 writein fraction form. We get

Now, we can multiply straight across. We get

Therefore, a quarter ofis.

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,ofis.

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,ofis.

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 writethree-quartersas a fraction.

Three-quartersis 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 ofis.

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,ofis.

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

So, in the problem

一半of

we will first write一半as a fraction. We know that一半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 ofis.

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,ofis.

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,ofis.

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

一半of 28

we will first write一半as a fraction. We know that一半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.

一半of 12

We will first write一半as a fraction. We know一半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.
