Most peeps had to use a ratio table to solve most of the questions. I also use equivalent fractions to make my answers shorter and easier to understand. My other strategy is long division.
I used the the ratio table to get the answer for 12 cups and also to get the price. Using my brain I multiplied 2 2/5 cups by 5 to get 12 cups. As for the price i also multiplied $3.60 by 5 and got $18.00.
I used the same thing but to get the answers i had to do some stuff.
First, I had to divide 2 2/5 by a number to get 1/2 but it was pretty hard so i had to use long division. I still didn't got the explanation but I got an answer. I still used the same denominator, 12, then I divided the cups for the ingredients by 2 using 12 as the denominator and i got 6 cups out of 12 cups. I can also use a ratio table and it will be much easier.
In this ratio table I started with the 2 2/5 cup until I got to 1 cup and found out the price for each cup.
I also found out different cups like for 3 cups, the price would be $4.50 as shown in the ratio table. I also found out the price for 1 cup, $1.50, by using the ratio table. If you multiply 12 by 2 and so is the price you'll get 24 cup with the price of $36.00.
