(a)/(b)

Basic fraction form

(a)/(b) + (c)/(d) = (ad + bc)/(bd)

Fraction addition

(a)/(b) × (c)/(d) = (ac)/(bd)

Fraction multiplication

(a)/(b) ÷ (c)/(d) = (a)/(b) × (d)/(c) = (ad)/(bc)

Fraction division

예제 1★☆☆☆☆

Calculate 1/2 + 1/3.

(1)/(2) + (1)/(3) = (3)/(6) + (2)/(6) = (5)/(6)

예제 2★☆☆☆☆

Calculate 2/3 ÷ 4/5.

(2)/(3) ÷ (4)/(5) = (2)/(3) × (5)/(4) = (10)/(12) = (5)/(6)
