Which fraction would you choose if you had to pick the larger piece: 3/8 or 1/4?
The answer is: 3/8
Yes, 3/8 is bigger than 1/4.
Here’s the quick proof: 1/4 = 2/8
So you’re really comparing: 3/8 vs. 2/8
Because 3 is greater than 2: 3/8 > 2/8
Therefore, 3/8 > 1/4.

Why Does 1/4 Become 2/8?
You might wonder why we can suddenly change 1/4 into 2/8.
We multiply both the numerator and denominator by 2:
×2 on bottom
This does not change the value of the fraction. It simply gives us an equivalent fraction with the same denominator as 3/8. Now both fractions are measured in eighths:
3/8 and 2/8
When fractions have the same denominator, the one with the larger numerator is greater. So, 3/8 is greater.
Check the Answer With Decimals
There’s another quick way to check.
Convert each fraction to a decimal:
So once again: 3/8 > 1/4
Both methods lead to the same answer.
Is 1/4 Bigger Than 3/8?
No.
1/4 is smaller than 3/8. In symbols: 1/4 < 3/8
You can see why by rewriting 1/4 as 2/8
And:
2/8 < 3/8
So the reverse comparison gives the same result.
How Much Bigger Is 3/8 Than 1/4?
We can find the difference by subtracting: 3/8 − 1/4
Since 1/4 = 2/8, so 3/8 − 2/8 = 1/8
So, 3/8 is exactly 1/8 greater than 1/4.
Don't decide which fraction is bigger by looking at the denominators alone.
You might think, “8 is bigger than 4, so 3/8 must be smaller.” But that's not how fraction comparison works.
The denominator tells you how many equal parts make up the whole. Make the denominators the same first.
