Unit Fraction x Proper Fraction 5-55

Multiply unit fractions and proper fractions by breaking proper fractions into unit fractions. What's 1/4 x 2/3? 2/3 = 1/3 + 1/3, so multiply 1/4 x (1/3 + 1/3) = 1/12 + 1/12 = 2/12 and 2/12 = 1/6. Algorithm? Multiply numerators to get the number of each part. Multiply denominators to get the size of each part. What's 3/4 x 1/2? (3x1)/(4x2) = 3/8.
