Learn what numerator and denominator mean, model fractions as parts of a whole, and place fractions on a number line.
A fraction names part of a whole. It is written as:
Denominator = total number of equal parts the whole is cut into.
Numerator = how many of those parts you are counting.
1. The fraction bar below has some parts shaded. Which fraction does it show?
Count the total parts (denominator) and the shaded parts (numerator). 2 parts are shaded out of 5 total → 2/5.
2. Which point on the number line is at 1/2?
1/2 is exactly halfway between 0 and 1. Point B sits right in the middle.
3. A chocolate bar is broken into 8 equal pieces. Maria eats 3 pieces. What fraction of the bar did she eat?
Pieces eaten = numerator (3). Total pieces = denominator (8). Fraction eaten = 3/8.
4. What is the value of the fraction where the numerator equals the denominator? (For example, 6/6 = ?)
6/6 means all 6 parts out of 6 total — that is the whole thing, which equals 1.
5. How many equal parts does a number line from 0 to 1 need to show the fraction 1/6?
The denominator tells you how many equal parts to divide the number line into. For 1/6, divide into 6 equal parts.
6. A ribbon is cut into 5 equal pieces. You use 4 pieces. Which fraction shows how much ribbon you used?
Used = 4 (numerator). Total = 5 (denominator). Fraction used = 4/5.
7. On a number line from 0 to 1, the fraction 3/4 is located how many equal jumps from 0 (out of 4 total jumps)?
3/4 means 3 jumps out of 4 equal jumps from 0 to 1. The numerator = the number of jumps.
