1. $ 1.2 \div 0.4 $

Multiply both numbers by 10 to eliminate decimals:
$$
(1.2 \times 10) \div (0.4 \times 10) = 12 \div 4 = 3
$$
✔ Answer: 3

2. $ 1.1 \div 0.11 $

Multiply both by 100:
$$
(1.1 \times 100) \div (0.11 \times 100) = 110 \div 11 = 10
$$
✔ Answer: 10

---

3. $ 0.64 \div 0.8 $

Multiply both by 10:
$$
(0.64 \times 10) \div (0.8 \times 10) = 6.4 \div 8
$$
Now divide:
$ 6.4 \div 8 = 0.8 $

✔ Answer: 0.8

---

4. $ 0.99 \div 0.11 $

Multiply both by 100:
$$
(0.99 \times 100) \div (0.11 \times 100) = 99 \div 11 = 9
$$
✔ Answer: 9

---

5. $ 0.049 \div 0.7 $

Multiply both by 1000:
$$
(0.049 \times 1000) \div (0.7 \times 1000) = 49 \div 700
$$
Now simplify:
$$
49 \div 700 = 0.07
$$

✔ Answer: 0.07

---

6. $ 24 \div 0.03 $

Multiply both by 100:
$$
(24 \times 100) \div (0.03 \times 100) = 2400 \div 3 = 800
$$
✔ Answer: 800

---

7. $ 0.56 \div 0.8 $

Multiply both by 10:
$$
(0.56 \times 10) \div (0.8 \times 10) = 5.6 \div 8 = 0.7
$$
✔ Answer: 0.7

---

8. $ 63 \div 0.7 $

Multiply both by 10:
$$
(63 \times 10) \div (0.7 \times 10) = 630 \div 7 = 90
$$
✔ Answer: 90

---

✔ Final Answers:

1. $ 1.2 \div 0.4 = \boxed{3} $
2. $ 1.1 \div 0.11 = \boxed{10} $
3. $ 0.64 \div 0.8 = \boxed{0.8} $
4. $ 0.99 \div 0.11 = \boxed{9} $
5. $ 0.049 \div 0.7 = \boxed{0.07} $
6. $ 24 \div 0.03 = \boxed{800} $
7. $ 0.56 \div 0.8 = \boxed{0.7} $
8. $ 63 \div 0.7 = \boxed{90} $
