---
4. [÷ Whole Numbers to 12]
Divide each number by 4:
- 16 ÷ 4 =
4
- 4 ÷ 4 =
1
- 24 ÷ 4 =
6
- 32 ÷ 4 =
8
- 8 ÷ 4 =

---
5. [Large Number +,–]
Subtract:
```
1360
– 230
-------
```
- 0 – 0 = 0
- 6 – 3 = 3
- 3 – 2 = 1
- 1 – 0 = 1
✔ Answer: 1130
---
6. [Large Number ×,÷]
840 ÷ 10 =
84
✔ Answer: 84
---
7. [Decimal +,–]
Add decimals:
```
5.2.3
+ 2.6.3
-------
```
Wait — this is likely a typo in formatting. It should be:
```
5.23
+ 2.63
------
```
But written as:
```
5 2.3
+ 2 6.3
```
So it’s:
- 5.23 + 2.63 = ?
Break it down:
- 5 + 2 = 7
- 0.23 + 0.63 = 0.86
So:
7.86
✔ Answer: 7.86
---
8. [Decimal ×,÷]
Multiply:
```
0.9
× 2
-----
```
0.9 × 2 =
1.8
✔ Answer: 1.8
---
9. [Fraction +,–]
$$
\frac{7}{9} - \frac{3}{9} = \frac{4}{9}
$$
✔ Answer: 4/9
---
10. [Fraction ×,÷]
$$
3 × \frac{1}{8} = \frac{3}{8}
$$
✔ Answer: 3/8
---
11. [Percentages]
"15 out of 100" as a percentage:
$$
\frac{15}{100} = 15\%
$$
✔ Answer: 15%
---
12. [Decimals / Fractions / Percentages]
The shape has 10 equal parts, and 7 are shaded.
So:
$$

13. [Integers]
Which location has the
lowest altitude?
- A) 1000 m above sea level → +1000
- B) 85 m below sea level →
–85
- C) 24 m above sea level → +24
Lowest (most negative) is
B)
✔ Answer: B) Death Valley (USA)
---
14. [Rates / Ratios]
Simplify ratio

$$
2^2 = 2 × 2
$$
✔ Answer: 2 × 2
---
16. [Order of Operations]
$$
12 + 8 – 9 = ?
$$
Left to right:
- 12 + 8 = 20
- 20 – 9 =
11
✔ Answer: 11
---
17. [Exploring Numbers]
Which is largest?
- A) 3086
- B) 3806

✔ Answer: 4, 8, 12, 16, 20
---
19. [Number Patterns]
Sequence: 6, 13, 20, 27, 34, __, __
Look at differences:
- 13 – 6 = 7
- 20 – 13 = 7
- 27 – 20 = 7
- 34 – 27 = 7
So add 7 each time:
- 34 + 7 =
41
- 41 + 7 =
48
✔ Answer: 41, 48
---
20. [Expressions]
Simplify: $ y + y $
=
2y
✔ Answer: 2y
---
21. [Substitution]
If $ y = 2 $, find $ y + 6 $
= 2 + 6 =
8
✔ Answer: 8
---
22. [Equations]
Solve: $ 4 + \boxed{} = 10 $
