## Answers:

1- **A**

\(8000 – 658 = 7342\)

2- **D**

\(14 × 40 = 560\)

3-** C**

24,589 is the sum of \(20,000; 4,000; 500; 80;\) and 9

4- **C**\(A = 44 – (21 + 9)\)

\(A = 14\)

5- **C**

In 1 day 4 meals so \(4 × 7 = 28\) meals a week.

6- **D**

\(A = 72 ÷ 8\)

\(A= 9 \)

7- **D**

the model for the first fraction is divided into 6 equal parts. We shade 3_6 to show the same amount as 1_2. The model for the second fraction is divided into 8 equal parts. We shade 3_ 8 that it shows these two models are different fractions.

8- **C**

The arrow shows exactly the middle of two numbers 35 and 45, so the answer is 40

9- **12**

\(108 ÷ 9 = 12\)

10- **C**

the model for the first fraction is divided into 8 equal parts. We shade 2_ 8 to show the same amount as 1_ 4. The model for the second fraction is divided into 16 equal parts. We shade 4_ 16 to show the same amount as 1_ 4.
