Bonjour

[tex]F=\dfrac{3}{8}-\dfrac{3}{14}\times\dfrac{7}{6}\\\\F=\dfrac{3}{8}-\dfrac{1}{14}\times\dfrac{7}{2}\\\\F=\dfrac{3}{8}-\dfrac{1}{2}\times\dfrac{1}{2}\\\\F=\dfrac{3}{8}-\dfrac{1}{4}\\\\F=\dfrac{3}{8}-\dfrac{2}{8}\\\\F=\dfrac{1}{8}[/tex]

F= 3/8 - 3/14 x 7/6 
=3/8-21/84
=3/8-7/28
=84/224-56/224
=28/224
=14/112
=7/56
=1/8

G= ( 2- 1/3 ) : 20/9
=(6/3-1/3) * 9/20
=5/3*9/20
=45/60
=3/4
