Answer: 37 yards (approx)
Explanation: STEP 1 Start by subtracting a greater multiple, such as 100 times the divisor. For example, you know that you can make at least 100 ft which is long 33 yards. Continue subtracting until the remaining number is less than the multiple, 3. STEP 2 Subtract smaller multiples, such as 3 times the divisor until the remaining number is less than the divisor. In other words, keep going until you no longer a remainder is left in the place of the remainder. Then add the partial quotients to find the quotient. So, there are 110 ft = 110 ÷ 3 = 36.6 yards = 37 yards (approx).
Divide. Use partial quotients.
Question 2. 3)\(\overline { 225 } \) ____
Explanation: STEP 1 Start by subtracting a greater multiple, such as 50 times the divisor. Continue subtracting until the remaining number is less than the multiple, 3. STEP 2 Subtract smaller multiples, such as 3 times the divisor until the remaining number is less than the divisor. In other words, keep going until you no longer a remainder is left in the place of the remainder. Then add the partial quotients to find the quotient. So, there are 50 x 3 = 150 : 225 – 150 = 75 3 x 25 = 75 : 75 – 75 = 0 Therefore the quotient is 75 ( 50 + 25)

Question 8: Compare Representations How many different ways can you write a fraction that has a numerator of 2 as a sum of fractions? Explain.
Answer: Let’s say we have the fraction 2/9. We can split this one fraction into two by modifying the numerator, like so: 2/9 = 1/9 + 1/9 This works because since both fractions have a numerator of 9, you can easily add the numerators to give 2, and that will give 2/9 in return. However, you can’t separate the denominators. 2/9 is not equal to 2/6 + 2/3 2/9 = 1/9 + 1/9 2/9 = 0.5/9 + 1.5/9 (which simplifies to 1/18 + 3/18, also giving 2/9) 2/9 = 0.5/9 + 0.5/9 + 0.5/9 + 0.5/9 = 1/18 + 1/18 + 1/18 + 1/18 I basically split it up into more and more fractions that add up to give 2/9. So, in short, there are infinitely many ways to do it.

Question 16. Alicia had 3 \(\frac{1}{6}\)yards of fabric. After making a tablecloth, she had 1 \(\frac{3}{6}\) yards of fabric. Alicia said she used 2 \(\frac{3}{6}\) yards of fabric for the tablecloth. Do you agree? Explain. ______
Answer: Yes
Explanation: An easier way to do this is to make the fractions improper fractions. 3 1/6 can be rewritten as 19/6. 1 4/6 can be rewritten as 10/6. Multiply the denominator by the number at its side, and add it to the numerator. 2 3/6 is 15/6. Subtract 10/6 from 19/6. 19/6-10/6=9/6. 9/6 is not 15/6, therefore she did not use 2 3/6 yards of fabric.

Question 3. Chad buys peanuts in 2-pound bags. He repackages them into bags that hold \(\frac{5}{6}\) pound of peanuts. How many 2-pound bags of peanuts should Chad buy so that he can fill the \(\frac{5}{6}\) -pound bags without having any peanuts left over? _________ 2-pound bags
Explanation: Given, Chad buys peanuts in 2-pound bags. He repackages them into bags that hold \(\frac{5}{6}\) pound of peanuts. \(\frac{5}{6}\) + \(\frac{5}{6}\) + \(\frac{5}{6}\) + \(\frac{5}{6}\) + \(\frac{5}{6}\) Thus 5 2-pound bags of peanuts are left.
Question 4. A carpenter has several boards of equal length. He cuts \(\frac{3}{5}\) of each board. After cutting the boards, the carpenter notices that he has enough pieces left over to make up the same length as 4 of the original boards. How many boards did the carpenter start with? _________
Explanation: Given, A carpenter has several boards of equal length. He cuts \(\frac{3}{5}\) of each board. After cutting the boards, the carpenter notices that he has enough pieces left over to make up the same length as 4 of the original boards. 4 of the original boards have a summed length of 20 units. 5 x 4 = 20. Since 2/5 is left from each board, you simply add them until the 2’s add to 20. So, 2 x 10 = 20. Hence, there are 10 2/5 boards. That’s just 4 of the boards that the 2/5 make up, but that should also mean that there are 10 3/5 boards as well. 30/5 + 20/5 = 50/5 = 10

Explanation: \(1 \frac{4}{9}+2 \frac{6}{9}\) = 4 \(\frac{1}{9}\) First add the whole numbers 1 + 2 = 3 4/9 + 6/9 = 10/9 Convert it into the mixed fractions 10/9 = 1 \(\frac{1}{9}\) 3 + 1 \(\frac{1}{9}\) = 4 \(\frac{1}{9}\) Thus the above statement is true.
Question 20. b. \(3 \frac{5}{6}+2 \frac{3}{6}\) is equal to 5 \(\frac{2}{6}\) i. True ii. False
Explanation: First add the whole numbers 3 + 2 = 5 5/6 + 3/6 = 8/6 Convert it into the mixed fractions 8/6 = 1 \(\frac{2}{6}\) 5 + 1 \(\frac{2}{6}\) = 6 \(\frac{2}{6}\) Thus the above statement is false.
Question 20. c. \(4 \frac{5}{8}-2 \frac{4}{8}\) is equal to 2 \(\frac{3}{8}\) i. True ii. False
Explanation: \(4 \frac{5}{8}-2 \frac{4}{8}\) First subtract the whole numbers 4 – 2 = 2 5/8 – 4/8 = 1/8 = 2 \(\frac{1}{8}\) Thus the above statement is false.
Question 20. d. \(5 \frac{5}{8}-3 \frac{2}{8}\) is equal to 2 \(\frac{3}{8}\) i. True ii. False
Explanation: \(5 \frac{5}{8}-3 \frac{2}{8}\) 5 – 3 = 2 5/8 – 2/8 = 3/8 = 2 \(\frac{3}{8}\) \(5 \frac{5}{8}-3 \frac{2}{8}\) = 2 \(\frac{3}{8}\) Thus the above statement is true.
