If you are asking about the numbers shown on elements the larger of the two numbers is the Mass Number ( the number of protons and neutrons added together) and the smaller number is the Atomic or Proton Number (the number of protons)
Top and bottom are also properties of Quarks along with Up & Down and Strange & Charm
Science-teacher
the numerator is the top number and the denominator is the bottom number
It is the bottom number the top number is the numerator :)
Top: numerator. Bottom: denominator.
putting the top number on bottom and bottom number on top
top
the numerator is the number on top and the number on the bottom is the denominator.
The top is the numerator, the bottom is the denominator.
At the bottom, the atomic number is at the top.
The qualities for a fraction are a numerator (the top number) divided by a denominator (the bottom number).
The answer depends on what the top and bottom number refer to!
A proper fraction is a fraction that has a top number less than its bottom number.
do you divide by the top or bottom number
