**Extended response questions:**  1. How can you tell if two fractions are equivalent? you find all the numbers that are equivalent and you see if any are the same or you divide 2. When is a fraction in simplest form? that means the they are divide as many times as they can and they can not go any lower

3. Why do you need to find a common denominator before adding or subtracting fractions?  because if the numbers are not in a comon denomenator then they do not add or subract and it is easyer 4. 1/2-->1/4 : 1/4-->1/8 AND 1/3-->1/6 : 1/6-->1/12 Why did you put that answer? What is the relationship between these pairs of fractions? I put that anserw because i saw that 1/6 had all ready been used so i put that anserw and also they all are half of the second fraction  5. Crozet Elementary teachers want students to only use #2 pencils or #2 mechanical pencils. To make that happen, the school will now provide all pencils, but we need to figure out what fraction of each kind the school should keep on hand. Several facts are known: 1. Mechanical pencils last twice as long as regular ones. 2. Mechanical pencils may only be used in grades 3, 4, and 5. 3. Mechanical pencils may not be used on bubble tests. 4. There are about the same number of students in grades K-2 as there are in grades 3-5. Using the information provided, what fraction of the total number of pencils should be mechanical pencils? Explain your decision in detail, using the facts. i think that they will need 1/2 regular and the other half mechanical pencils because i used prosess of elimonation and my results told me that they should split it 50 50.
