## Answers:

1- **B**

An easy way to tell whether a large number is odd or even is to look at its final digit. If the number ends with an odd digit \((1, 3, 5, 7, or\space 9)\), then it’s odd. On the other hand, if the number ends with an even digit or \(0 (0, 2, 4, 6\space or\space 8)\), then it is even.

\(15, 29,\) and \(83\) end with odd digits, so they are odd numbers.

2- **D**

She saves \($36\) and \($28\) so she has \($64\).

\($140 – $64 = $76\) she needs to save.

3- **D**

Michelle divides \(72\) books into \(9\) boxes therefore \(72 ÷ 9\) formula is correct.

4- **B**

Eva gave \(349\) of her \(983\) cards to her friend so her cards are \(983-349\), then she lost \(260\) cards so now she has \(983-349-260=374\) cards.

5- **D**

Use the formula of a rectangle:

\(Area= length × width\)

Area \(=3cm×7cm =21cm^2\)

6- **B**

Add \(4\) hundred and \(8\) tens and \(4\) ones

So we have :\(400 + 80 + 4 = 484\)

7- **A**

The chances of landing on red are \(3\) in \(6\)

The chances of landing on yellow are \(1\) in \(6\)

The chances of landing on the green are \(2\) in \(6\)

The chances of landing on red are more than in other colors.

8- **C**

\(32\) inches distance most occur in this table.

9- **A**

10- **C**

All these equations are true:

\(98 – 31 = Z\)

\(98 – Z = 31\)

\(Z + 31 = 98\)
