Mr. Alvarez shares \(54\) stickers equally among \(6\) folders. Which equation matches the story: \(54\div6\) or \(6\div54\)? Explain what the answer means, then solve.

Hints

- Ask which number is the total number of stickers. - Ask how many equal groups there are. - The answer should tell how many stickers go in each folder.

Solution

1. The total of \(54\) stickers is being shared among \(6\) equal folders, so the matching equation is \(54 \div 6\). 2. \(54 \div 6 = 9\). 3. The answer tells how many stickers go in each folder.

Answer

\(54 \div 6 = 9\). Each folder gets \(9\) stickers.

Six cartons hold \(7\) juice boxes each. Write an equation using \(n\) for the total number of juice boxes. Then find \(n\) and explain what it represents.

Hints

- Decide what quantity \(n\) should represent before writing the equation. - The cartons are equal groups, so use the number of cartons and the number in each carton. - After solving, state what the value of \(n\) means in the situation.

Solution

1. Six equal cartons with \(7\) juice boxes each are represented by \(n=6 \times 7\). 2. \(6 \times 7=42\), so \(n=42\). 3. The value \(42\) is the total number of juice boxes in all six cartons.

Answer

\(n=6 \times 7\), so \(n=42\). The \(42\) represents the total number of juice boxes.

Solution

1. One possible question is, “How many scissors are placed at each table?” 2. Divide equally: \(32 \div 8 = 4\).

Answer

Question: “How many scissors are placed at each table?” Answer: Each table gets \(4\) scissors.
5211863
Leah has \(32\) trading cards. She wants to share them equally among \(4\) friends. Leah says, “Each of you will get \(9\) cards.” Is Leah correct? Explain with an equation.

Hints

- Use a related multiplication fact to check the claim. - If \(32\) cards are split into \(4\) equal groups, how many cards are in each group? - What is \(4 \times 9\)? - How many cards would Leah need for each friend to receive \(9\)?

Solution

1. Divide the total number of cards by the number of friends: \(32 \div 4 = 8\). 2. Leah’s claim would require \(4 \times 9 = 36\) cards. 3. Because she has only \(32\) cards, Leah is not correct. Each friend gets \(8\) cards.

Answer

No. Each friend gets \(8\) cards because \(32 \div 4 = 8\).

Jonah says, “More loaves of bread were sold on Wednesday than on Tuesday.” Check his statement and correct it.
Figure for problem 538126

Hints

- Read the Tuesday and Wednesday values. - Pay attention to the word “more.” - Subtract to state the corrected comparison exactly.

Solution

1. The graph shows \(15\) loaves on Wednesday and \(18\) loaves on Tuesday. 2. Since \(15 < 18\), Jonah's statement is false. 3. The difference is \(18 - 15 = 3\).

Answer

The statement is false. On Wednesday, \(3\) fewer loaves were sold than on Tuesday.
5381333
Six teams collect bags of recyclables. Which teams collected at least \(10\) bags but no more than \(15\) bags?

Mara reads Bar C as \(9\). Explain her error and give the correct value.
Figure for problem 538140

Hints

- First determine how much each tick interval represents. - Match the top of Bar C to a scale value. - Check your reading by counting in fives.

Solution

1. The scale increases by \(5\) at each tick mark, not by \(1\). 2. Bar C ends at the ninth interval above \(0\), so its value is \(9 \times 5 = 45\).

Answer

Mara counted tick intervals instead of scale values. The correct value is \(45\).
5381583
A mystery tree has a bar taller than the spruce bar but shorter than the pine bar. It is also not the shortest bar. Which tree is it?
Figure for problem 538158

Hints

- Read the spruce and pine values from the scale. - Find the bar whose value lies strictly between those two values. - Check the final condition against the shortest bar.

Solution

1. The spruce has a value of \(15\), and the pine has a value of \(25\). 2. The only bar with a value between \(15\) and \(25\) is the fir at \(20\). 3. The fir is not the shortest bar, so it satisfies every condition.

Answer

The mystery tree is the fir.
5381653

Answer

One possible question is, “How many more leaves did David collect than Alma?”
5503623
Seven boxes hold \(8\) pencils each. Noah says the total is \(7 + 8\). Ava says the total is \(7 \times 8\). Who is correct? Explain and find the total number of pencils.

Hints

- What do \(7\) and \(8\) each mean in the story? - Are there \(7\) equal groups of \(8\), or are the numbers simply being joined? - Choose the equation that matches the equal groups.

Solution

1. The boxes are equal groups of \(8\) pencils, repeated \(7\) times. 2. Multiplication represents equal groups, so Ava's equation is correct: \(7 \times 8 = 56\). 3. Adding \(7 + 8\) combines the number of groups with the size of one group, so it does not represent the situation.

Answer

Ava is correct. The \(7\) boxes are \(7\) equal groups of \(8\) pencils, so \(7\times8=56\). The addition \(7+8\) does not represent seven groups of eight.
