Answer:
A) 7/4 cans of paint left, or 1 and 3/4 cans left
B) 8 posters
C) 1/8 of a can
D) 2/4 of a can or 1/2 of a can
Explanation:
A) You use 1/4 of a can to make a poster. if you just make 1 and start with 2 cans , that means you start with 8/4. so if you use up 1/4 you have 7/4 left. or 1 and 3/4.
B) Each poster takes 1/4 of a can of paint. With two cans just count by 1/4 until you get to 2. so 1/4 + 1/4 = 2/4 + 1/4 = 3/4 + 1/4 = 4/4 and so on. it works out that you can make a total of 8 posters.
This is also a division problem two cans of paint divided by 1/4 for each poster. it works out to 2*4 = 8, though if you do not know fraction multiplication/ multiplication that's fine. if you would like me to explain let me know.
C) 1/4 makes two. Assuming each poster uses the same amount, we would know 1 would take half of that. cutting 1/4 in half makes 1/8 so one poster takes 1/8 of a can of paint. so 1/8 for 1 poster.
D) 1/4 of a can of paint makes 1 poster. so two poster uses twice as much. 2/4 or 1/2 of a can of paint.
