Bonjour !
a)
[tex]11x=88,44\\ x = \frac{88.44}{11} = 8.04[/tex]
b)
[tex]7x = 714 \\ x = \frac{714}{7} = 102[/tex]
c)
[tex] \frac{x}{3} = 15 \\ x = 3 \times 15 = 45[/tex]
d)
[tex] \frac{x}{10 } = 270 \\ x = 10 \times 270 = 2700[/tex]
e)
[tex]6x = 15.3 \\ x = \frac{15.3}{6} = 2.55 [/tex]
f)
[tex]15.6 = 6 + x \\ x = 15.6 - 6 = 9.6[/tex]
Bonne soirée
