Fractions: Numerator, Denominator, and Comparing Fractions

Mathematics Grade 4 Difficulty 2/5

Beginning of the lesson

Understanding Fractions: Numerator and Denominator

What is a Fraction? A fraction represents a part of a whole. It shows us how many equal pieces we have out of a total number of equal pieces.

Parts of a Fraction

Every fraction has two important parts separated by a line:

3 ← Numerator (Числитель)
4 ← Denominator (Знаменатель)
The Fraction Bar means "divided by" or "out of"
3 out of 4 parts shaded = 3/4

The Numerator (Числитель)

The "Counter" - Top Number

The numerator tells us HOW MANY parts we have or are talking about.

  • It's the number on TOP of the fraction bar
  • It counts the parts we're interested in
  • Think of it as the "counter" - it counts!
Example: In the fraction 5/8, the numerator is 5
This means we have 5 parts out of the total.
