Visual Understanding
Why Same Denominators?
1/3 + 1/4 = ?
Thirds and quarters are different sizes!
Need same-sized pieces: twelfths
4/12 + 3/12 = 7/12
Why Multiply Works
1/2 × 1/3 = "half of a third"
= 1/6 of the whole
Taking a fraction OF a fraction
makes it smaller
Why Division = Flip & Multiply
How many 1/4s in 1/2?
1/2 ÷ 1/4 = 1/2 × 4/1 = 2
Two quarters make a half
Division asks "how many?"
Practice questions for Fraction Operations
Which of these fractions is the largest? ⅔ ¾ ⅗ ⅝
Explain why you need a common denominator when adding fractions, but not when multiplying fractions.
