Bonjour, j'aurais besoin d'un coup de main en maths car je bloque, merci d'avance. Complèter les calculs suivants en passant par l'écriture décimale:
3/10 + 5/10 = 0.3 + 0.5 + = 0.8 = 8/10
84/10 - 65/10 = ............... - ................ = .................... = ................. = ....../......
154/100 + 623/100 = ................. = ................. = ....../........
Merci d'avance :)
