Solution for problem 1
First you have to make 3 2/8 an improper fraction by multiplying 3 and 8 and then adding 2.Next you keep the denominator the same as the original fraction, so the answer to that would be 26/8. After that, you need to make 2 an improper fraction by just putting a 1 under the 2. Since 2 is a numerator and 8 is a denominator you can simplify them both by 2, which would and give you 26/4. Lastly, you would make 26/4 a mixed number by dividing 4 into 26. The answer to that is 6 2/4, but you can simplify that to 6 ½! And that is your answer.
Solution for problem 2
In this problem you are adding. You have to first line the problem up horizontally and then you have to change the denominators so they are the same. So now the denominators are 12 and the numerators are 6 and 6. After that you just add the numerators because the denominators are already the same. After you do that you have to add the whole numbers. Now the numbers you have are 16 and 1. You take those 2 numbers and add them so your answer is 17!
Solution for problem 3
Here you have a division problem and first you keep ¾ the same and since you have a whole number you have to change it to an improper fraction by placing a one under the twelve. Then you reverse (reciprocal) the order of 12/1 to 1/12. Now you make the division sign a multiplication sign and then multiply.
Solution for problem 4
In this problem you are doing division, so you first need to make 25 12/100 an improper fraction which would be 2512/100 and then place a one underneath the whole number twelve. But then you are going to reverse the order of the twelve and the one. Now you change the division sing to a multiplication sign and then multiply. ( before the division you have to find the circumference of the cake C * 3.14 )
Solution for problem 5
In this problem you will be subtracting, you subtract 12-7 ¾. You do that by lining up the two numbers horizontally. After that you add 4/4 next to the 12 because you have to have a fraction next to a whole number when subtracting, and you also want to have a fraction with the same denominator as the fraction below it. And all you have to do now is subtract! Now you would have ¼ as the fraction and all you would have to do is subtract the numerators. So your answer would be 5 ¼!
Solution for problem 6
Here we have an addition problem and first what you would do is look at the denominators and determine the G.C.F. of each. In this case the G.C.F. would be 12 so then you times the other numerators by how ever many it took to reach 12 from each of the denominators and now you will add the numerators together. Here you would get 1 2/3
