To solve the division sentences for each array, we need to count the total number of items in the array and then determine how many groups or rows/columns there are. The division sentence will describe how the total is divided into equal parts.
Let's go through each problem step by step:
---
Problem 1:
```
8 ÷ 2 = ?
```
-
Array: There are 8 blue circles arranged in 2 rows.
-
Total items: 8
-
Number of rows: 2
-
Division sentence: \( 8 \div 2 = 4 \)
Answer: \( 8 \div 2 = 4 \)
---
Problem 2:
```
15 ÷ ? = 3
```
-
Array: There are 15 orange dots arranged in 3 rows.
-
Total items: 15
-
Number of rows: 3
-
Division sentence: \( 15 \div 5 = 3 \)
Answer: \( 15 \div 5 = 3 \)
---
Problem 3:
```
? ÷ 4 = 5
```
-
Array: There are 20 yellow stars arranged in 4 rows.
-
Total items: 20
-
Number of rows: 4
-
Division sentence: \( 20 \div 4 = 5 \)
Answer: \( 20 \div 4 = 5 \)
---
Problem 4:
```
9 ÷ 3 = ?
```
-
Array: There are 9 pink flowers arranged in 3 rows.
-
Total items: 9
-
Number of rows: 3
-
Division sentence: \( 9 \div 3 = 3 \)
Answer: \( 9 \div 3 = 3 \)
---
Problem 5:
```
? ÷ 3 = 4
```
-
Array: There are 12 brown arrows arranged in 3 rows.
-
Total items: 12
-
Number of rows: 3
-
Division sentence: \( 12 \div 3 = 4 \)
Answer: \( 12 \div 3 = 4 \)
---
Problem 6:
```
? ÷ 5 = 2
```
-
Array: There are 10 purple dots arranged in 5 rows.
-
Total items: 10
-
Number of rows: 5
-
Division sentence: \( 10 \div 5 = 2 \)
Answer: \( 10 \div 5 = 2 \)
---
Problem 7:
```
4 ÷ 2 = ?
```
-
Array: There are 4 green hearts arranged in 2 rows.
-
Total items: 4
-
Number of rows: 2
-
Division sentence: \( 4 \div 2 = 2 \)
Answer: \( 4 \div 2 = 2 \)
---
Problem 8:
```
? ÷ 4 = ?
```
-
Array: There are 16 gray squares arranged in 4 rows.
-
Total items: 16
-
Number of rows: 4
-
Division sentence: \( 16 \div 4 = 4 \)
Answer: \( 16 \div 4 = 4 \)
---
Final Answers:
1. \( 8 \div 2 = 4 \)
2. \( 15 \div 5 = 3 \)
3. \( 20 \div 4 = 5 \)
4. \( 9 \div 3 = 3 \)
5. \( 12 \div 3 = 4 \)
6. \( 10 \div 5 = 2 \)
7. \( 4 \div 2 = 2 \)
8. \( 16 \div 4 = 4 \)
\boxed{4, 5, 20, 3, 12, 10, 4, 16}
