**Extended response questions:**  1. How can you tell if two fractions are equivalent? first say there is a fraction 1/2 then u x each (numerater and denomerator) say by 2 1 becomes 2 and 2 becomes 4 2/4 is equal to 1/2

2. When is a fraction in simplest form? when it's like this 1/2

3. Why do you need to find a common denominator before adding or subtracting fractions?  because when you add/subtract fractions you only add/subtract the top number, so... EXAMPLE: 1/2 + 5/7 = it can't be two numbers you don't add the denomerator!!!!! 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 numerators are the same. In each pair of colors they are multibils EXAMPLE: 2x2+4  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 50% Or 5/10 should be macanical and the rest should be real, because in the k-2 and 3-5 they said have around the same amount of kids, And they said that macanical pencils may only be used in 3,4 and 5 since they have around the same amout of kids in should be 50% 50%
