Top number or bottom number?
A fraction has two numbers. One sits above the line and one sits below it.
The top one counts the parts you have. The bottom one says how many equal parts make a whole.
Here is a way to remember it. The word "denominator" and the word "down" both start with a D.
So in 3/4 the 3 is on top. You have 3 parts. The 4 below means the whole was cut into 4 equal parts.
What the top number tells you
Compare the two numbers and you can picture the fraction.
A smaller top number means less than one whole. In 2/5 you have 2 of the 5 parts.
A matching pair means exactly one whole. 4/4 is the same as 1.
A larger top number means more than one whole. 7/4 is one whole and 3 parts more.
A top number of 0 means you have none of the parts. So 0/6 is worth 0.

❓Numerator FAQ
Is the numerator the top or bottom number?
The top. It sits above the line. The bottom number is the denominator.
What does the numerator tell you?
How many parts you have. In 3/8 you have 3 parts out of 8 equal parts.
Can a numerator be bigger than the denominator?
Yes. That makes an improper fraction, which is worth more than one whole. 7/4 is an example.
Can a numerator be zero?
Yes. It means you have none of the parts, so the fraction is worth 0. The denominator is the one that can never be zero.
How do I remember which number is which?
Denominator and down both start with a D. So the denominator is the one down below, and the other one is on top.
