Bonjour
Je souhaite obtenir de l'aide pour un devoir de maths en anglais.
Je vous remercie d'avance

Miranda puts up wallpaper on the wall of her living room. On the first day, she sticks the wallpaper on 4/15 of the wall.
On the first day, she sticks another 2/5 of the total, and on the third day, 7/30.
Did she finish the pose ?
merci

Bonsoir,

4/15 + 2/5 + 7/30 = 8/30 + 12/30 + 7/30 = 27/30 = 9/10   < 1

No, she didn't finish the pose ....

Voici la réponse: She didn’t finish the pose. For calculate we have to put all the number on 30 so 4/15fois2 =8/30+2/5fois6=12/30+7/30. 8/30+12/30+7/30=27/30. So she didn’t finish the pose yet
