This is actually a ratio problem. I know they can get very confusing at times… But here we go!
First, find the greatest common factor that both 12 and 18 share, so...
12 18
1 x 12 1 x 18
2 x 6 2 x 9
3 x 4 3 x 6
BINGO! It is 6.
So that means there has to be 6 bags.
There are 6 bags in total.
So....how many apples go in each bag? Well, we know there are a total of 6 bags. We can either count the apples out or use division. Since we are not sitting at the dining room table counting out real apples,
let's do it by division.
12 apples divided by 6 bags = The number of apples that are in each bag.
12/6 = 2 apples in each bag.
So....how many granola bars are in each bag? Well, again, we know there are a total of 6 bags. And, once again, we can either count the granola bars out or use division. Since we don't have any granola bars in front of us.....Well, maybe you do but I don't!....let's do it by division again, shall we?
18 granola bars divided by 6 bags = The number of granola bars that are in each bag.
18/6 = 3 granola bars in each bag.
THEREFORE: Each bag has 2 apples and 3 apples in each bag.
Another way to solve it is like this…
12 apples in 6 bags is to 18 granola bars in 6 bags
Or you can write it this way…
12/6 : 18/6 Lets say it....12 applies divided by 6 apples is to 18 granola bars divided by 6 bags.
2 : 3 This is the ratio!
THEREFORE: 2 to 3 OR or for every 2 apples in each of the 6 bags, there will be 3 granola bars in each of the 6 bags.
Or the really fun way to figure this out is to buy 12 apples and 18 granola bars. Divide them out visually on the table. Get the answer and then have you and your friends and your family eat the apples and the granola bars!
Whichever way you choose… HAVE FUN!
