Answer:
4. 3 cans of paint will cover 60% of Dalia's room
5. Dalia's entire room requires 5 cans of paint
Step-by-step explanation:
If Dalia has painted 1/10 of her room with 1/2 can of paint, then she will paint 2/10 of her room with 1 can of paint (since there are 2 halves in a whole).
2/10 = 1/5 ⇒ 1 can of paint covers 1/5 of the room.
Therefore, to paint the entire room, she will need 5 cans of paint.
60% of 5 cans of paint = 0.6 × 5 = 3
Therefore, 3 cans of paint will cover 60% of the room.
