Simple Example
Quick Example
Imagine you have a delicious pizza cut into 8 equal slices. If you eat 5 of those slices, you have eaten 5/8 of the pizza. The '5' tells you how many slices you ate, and the '8' tells you the total number of slices the pizza had.
Worked Example
Step-by-Step
PROBLEM: You have a chocolate bar with 8 equal squares. If you eat 3 squares and your friend eats 2 squares, what fraction of the chocolate bar did you and your friend eat together? --- STEP 1: Identify the total number of equal parts. The chocolate bar has 8 equal squares. This is our denominator. --- STEP 2: Identify the number of parts eaten by you. You ate 3 squares. --- STEP 3: Identify the number of parts eaten by your friend. Your friend ate 2 squares. --- STEP 4: Add the parts eaten together. 3 + 2 = 5 squares. This is our numerator. --- STEP 5: Write the fraction. The fraction of the chocolate bar eaten together is 5/8. --- ANSWER: You and your friend ate 5/8 of the chocolate bar.

Common Mistakes
MISTAKE: Thinking 5/8 means '5 divided by 8' in a way that the answer is always less than 1. | CORRECTION: While 5/8 is less than 1, fractions can also be improper (like 8/5), meaning they represent more than one whole. 5/8 specifically means 5 parts out of 8 total parts.
MISTAKE: Confusing the numerator and the denominator. Forgetting which number represents the parts and which represents the total. | CORRECTION: The top number (numerator, 5) tells you 'how many parts you have'. The bottom number (denominator, 8) tells you 'how many equal parts make up the whole'.
MISTAKE: Assuming 5/8 is the same as 8/5. | CORRECTION: 5/8 means 5 parts out of 8, which is less than a whole. 8/5 means 8 parts out of 5, which is more than a whole (one whole and three-fifths more). They are very different!
