F= 3/8 - 3/14 x 7/6 =?? Aidez moi c'est urgent. G= ( 2- 1/3 ) : 20/9 =?? Aidez moi c'est urgent. Veuillez decomposé les calculs merci :) . 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] [tex]G= ( 2- \dfrac{1}{3}) : \dfrac{20}{9}\\\\G= ( \dfrac{6}{3}- \dfrac{1}{3})\times\dfrac{9}{20}\\\\G= \dfrac{5}{3}\times\dfrac{9}{20}\\\\G= \dfrac{1}{3}\times\dfrac{9}{4}\\\\G= \dfrac{1}{1}\times\dfrac{3}{4}\\\\G= \dfrac{3}{4}[/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
