Two groups went on a field trip. The teachers brought several of the same size sandwich. In one group, each student ate ¾ of a sandwich. In another, they each ate ⅚. Was it fair? How do you know?

It is not fair because ⅙ is smaller than ¼. If that is true, then ⅚ is bigger than ¾.

adding and subtracting

100

4/6+3/3

First multiply 3/3 by 2. This will get you to 6/6. Then add 4/6 plus 6/6. Your answer will be 10/6. 

200

How would you add ⅔ plus 3/3?

Add the numerators together and keep the denominator the same. 

The answer is 5/3.

300

Solve for ¾ - ⅓

Solve for ¾ - ⅓ 

1. Multiply ¾ by 3 and ⅓ by 4 in order to make the denominators the same. 

2. The new equation will be 9/12 -4/12.

3. Subtract the numerators and keep the denominators the same. 

4. Your answer will be 5/12.

300

⅓ + 2/6 + 1/12 ?

Solve and explain how you got your answer.

1. Multiply ⅓ by 4. Multiply 2/6 by 2. 

2. Your new fractions will be 4/12 and 4/12.

3. Now add 4/12 plus 4/12 plus 1/12. 

4. The answer is 9/12. 

500

Subtract ⅚ -½

1. Multiply ½ by 3 and it will get you to 3/6 

2. Your new equation will be ⅚-3/6

3. Subtract the numerators, and you will get 2/6.
