**Extended response questions:**  1. How can you tell if two fractions are equivalent?First simpilfy them then see if they're the smae fraction.

2. When is a fraction in simplest form?When it can not get any smaller

3. Why do you need to find a common denominator before adding or subtracting fractions?becouse if you don't then they you will not be in their simplist form.  4. 1/2-->1/4 : 1/4-->1/8 AND 1/3-->1/6 : 1/6--> _ Why did you put that answer? What is the relationship between these pairs of fractions?The first pair is not equivalent becouse 1/2 is like having half of the cake and if you have 1/4 is like having a quorter of the cake so they're are diffrent.1/4 is different than 1/8 becouse their both simplefied and their still differet from each other. 1/4 and 1/6 are different becouse their both simplifid and their not the same 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. Half of the school becouse only grades 3,4,5 can use them becouse it said only grads 3,4,5 can use them
