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 $$83$$ ends 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 are formula of 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:
$$98 – 31 = Z$$
$$98 – Z = 31$$
$$Z + 31 = 98$$
