How to Multiply Fractions

What You'll Learn

  • The basic rule for multiplying fractions
  • How to simplify your answer
  • Working with mixed numbers
  • Real-world examples

Step 1: Multiply the Numerators

The numerator is the top number in a fraction. To multiply fractions, first multiply the numerators together.

2 3 × 4 5

Multiply numerators: 2 × 4 = 8

Step 2: Multiply the Denominators

The denominator is the bottom number. Multiply the denominators together.

Multiply denominators: 3 × 5 = 15

8 15

Step 3: Simplify (if needed)

Check if your answer can be simplified by finding the greatest common divisor (GCD).

6 8 3 4

Both 6 and 8 can be divided by 2

Solve: 1 4 × 2 3

How to Add Fractions

What You'll Learn

  • Adding fractions with same denominators
  • Adding fractions with different denominators
  • Finding common denominators
  • Simplifying results

Same Denominators

When denominators are the same, just add the numerators!

1 5 + 2 5 = 3 5

Different Denominators

Find a common denominator first, then add the numerators.

1 2 + 1 3

Common denominator: 6

3 6 + 2 6 = 5 6

How to Subtract Fractions

What You'll Learn

  • Subtracting fractions with same denominators
  • Subtracting fractions with different denominators
  • Working with borrowing
  • Simplifying results

Same Denominators

When denominators are the same, subtract the numerators!

4 7 - 2 7 = 2 7

Different Denominators

Find a common denominator first, then subtract the numerators.

3 4 - 1 6

Common denominator: 12

9 12 - 2 12 = 7 12

How to Divide Fractions

What You'll Learn

  • The "flip and multiply" rule
  • Finding reciprocals
  • Simplifying division problems
  • Real-world division examples

The Magic Rule: Flip and Multiply!

To divide fractions, flip the second fraction and multiply instead!

2 3 ÷ 4 5 2 3 × 5 4

Flip 4/5 to get 5/4, then multiply!

Complete the Multiplication

Now multiply as you learned in the multiplication lesson!

2×5 3×4 = 10 12 = 5 6

Simplified by dividing both by 2
