Sagot :
D=4/5 - 3/10
=8/10-3/10
=5/10
=1/2
E=2+1/3
=6/3+1/3
=7/3
F=2/5+1/10-3/20
=8/20+2/20-3/20
=7/20
D=4/5 - 3/10
=8/10-3/10
=5/10
=1/2
E=2+1/3
=6/3+1/3
=7/3
F=2/5+1/10-3/20
=8/20+2/20-3/20
=7/20
Exercice pour mon D.M : URGENT !! Calculer et donner le résultat sous la forme d'une fraction la plus simple possible : D=4/5 - 3/10 ; E=2+1/3 ; F=2/5+1/10-3/20.
D=4/5 - 3/10
=8/10-3/10
=5/10
=1/2
E=2+1/3
=6/3+1/3
=7/3
F=2/5+1/10-3/20
=8/20+2/20-3/20
=7/20
D=4/5 - 3/10
=8/10-3/10
=5/10
=1/2
E=2+1/3
=6/3+1/3
=7/3
F=2/5+1/10-3/20
=8/20+2/20-3/20
=7/20
