Sagot :
(5/2 - 1/4) * 5/6 - (3- 7/6) = (10/4-1/4)*5/6-(18/6-7/6)
= 9/4*5/6-11/6
= 45/24-11/6
= 45/24-44/24
= 1/24
= (10/4-1/4) x 5/6-(18/6-7/6)
= 9/4 x 5/6-11/6
= 45/24-11/6
= 45/24-44/24
= 1/24
Ecrire sous la forme d'une fraction la plus simple possible :
(5/2 - 1/4) * 5/6 - (3- 7/6)
(5/2 - 1/4) * 5/6 - (3- 7/6) = (10/4-1/4)*5/6-(18/6-7/6)
= 9/4*5/6-11/6
= 45/24-11/6
= 45/24-44/24
= 1/24
= (10/4-1/4) x 5/6-(18/6-7/6)
= 9/4 x 5/6-11/6
= 45/24-11/6
= 45/24-44/24
= 1/24
