What you’ll learn

  1. A Fraction of a FractionUnderstand that multiplying fractions means taking a part of a part, and that 'of' means multiply.Multiplying fractions means finding a fraction OF another fraction. The word 'of' is a hidden multiply sign: 1/2 of 1/2 is 1/2 × 1/2 = 1/4. Because each fraction is less than one whole, the answer is smaller than both — a part of a part is always a tinier part.
  2. Multiply AcrossMultiply two fractions by multiplying the numerators and denominators straight across, then simplify.To multiply fractions, multiply the tops together and the bottoms together. For 2/3 × 3/4: 2 × 3 = 6 on top and 3 × 4 = 12 on the bottom, giving 6/12, which simplifies to 1/2. An area model shows why: the overlap of 2/3 one way and 3/4 the other covers 1/2 of the whole.
  3. In the Real WorldUse fraction multiplication to solve everyday problems with recipes, area, and shares.Fraction multiplication shows up whenever you take part of a part: halving a recipe that calls for 3/4 cup gives 1/2 × 3/4 = 3/8 cup, and planting 2/3 of a field that is 3/4 fenced covers 1/2 of it. Each real problem becomes a fraction times a fraction, solved by multiplying straight across.

Questions this course answers

In math, the word 'of' in '1/2 of 1/2' tells you to do what?

'Of' means multiply, so '1/2 of 1/2' is 1/2 × 1/2.

You multiply 1/2 × 1/2 and get 1/4. Compared to 1/2, the answer 1/4 is...?

Taking a part of a part makes a smaller piece, so 1/4 is smaller than 1/2.

What is 2/3 × 3/4 in its simplest form?

2 × 3 = 6 on top and 3 × 4 = 12 on the bottom; 6/12 simplifies to 1/2.

What is 1/2 × 3/4?

1 × 3 = 3 on top and 2 × 4 = 8 on the bottom, giving 3/8.

What is 1/3 × 1/2?

1 × 1 = 1 on top and 3 × 2 = 6 on the bottom, so the answer is 1/6.

You break a bar in half, then break that half in half. Each tiny piece is what fraction of the whole bar?

Half of a half is 1/2 × 1/2 = 1/4 of the whole bar.
