What happens when you split 5/8 into two equal parts? You get a smaller fraction—but what exactly is it?
Half of 5/8 is 5/16.
Here is the quick calculation:
So, what is half of 5/8 in fraction? The answer is 5/16.
How Do You Find Half of 5/8?
Finding half of a fraction means multiplying it by 1/2. This is because taking half of something is the same as dividing it by 2.
Start with:
Rewrite division by 2 as multiplication by 1/2:
Now multiply the numerators and denominators:
Therefore:
1/2 of 5/8 = 5/16
Why Does the Denominator Change from 8 to 16?
This is where the answer becomes easier to understand.
The fraction 5/8 means that a whole is divided into 8 equal parts, and you have 5 of those parts.
When you take half of those 5 eighths, you split each eighth into two equal pieces. Each new piece is therefore 1/16 of the whole.
So:
That is why the answer is 5/16.
A Quick Way to Remember It
When the numerator is odd and you want to find half of a fraction, multiplying by 1/2 is always a safe method:
For this problem:
So you can think of it as doubling the denominator while keeping the numerator the same in this particular case.
Just remember that this shortcut works directly here because the resulting fraction is already in its simplest form.
Check the Answer as a Decimal
You can also check the answer using decimals.
Common Mistake
A common mistake is to think that half of 5/8 is 5/8 ÷ 2 = 5/4 by dividing only the numerator. That changes the value in the wrong direction.
