Explications étape par étape

Bonsoir

Addition :

$\dfrac{a}{c} + \dfrac{b}{c} = \dfrac{a + b}{c}$

Soustraction :

$\dfrac{a}{c} - \dfrac{b}{c} = \dfrac{a - b}{c}$

Multiplication :

$\dfrac{a}{b} \times \dfrac{b}{c} = \dfrac{a \times b}{c \times b} = \dfrac{a}{c}$

Division :

$\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}} = \dfrac{a}{b} \times \dfrac{d}{c} = \dfrac{ad}{bc}$
