Let's solve each of these decimal division problems. The key idea is to
convert the divisor (the number we're dividing by) into a whole number by multiplying both the dividend and divisor by the same power of 10, so that we can divide more easily.

Problem 1: 1.64 ÷ 0.04
To eliminate the decimal in the divisor (0.04), multiply both numbers by 100:
- $ 1.64 × 100 = 164 $
- $ 0.04 × 100 = 4 $
Now divide:
- $ 164 ÷ 4 = 41 $
✔ Answer: 41

Problem 2: 0.30 ÷ 0.06
Multiply both by 100:
- $ 0.30 × 100 = 30 $
- $ 0.06 × 100 = 6 $
Now divide:
- $ 30 ÷ 6 = 5 $
✔ Answer: 5

Problem 3: 0.66 ÷ 0.03
Multiply both by 100:
- $ 0.66 × 100 = 66 $
- $ 0.03 × 100 = 3 $
Now divide:
- $ 66 ÷ 3 = 22 $
✔ Answer: 22

Problem 4: 1.50 ÷ 0.02
Multiply both by 100:
- $ 1.50 × 100 = 150 $
- $ 0.02 × 100 = 2 $
Now divide:
- $ 150 ÷ 2 = 75 $
✔ Answer: 75

Problem 5: 0.08 ÷ 0.02
Multiply both by 100:
- $ 0.08 × 100 = 8 $
- $ 0.02 × 100 = 2 $
Now divide:
- $ 8 ÷ 2 = 4 $
✔ Answer: 4
---
Problem 6: 0.64 ÷ 0.08
Multiply both by 100:
- $ 0.64 × 100 = 64 $
- $ 0.08 × 100 = 8 $
Now divide:
- $ 64 ÷ 8 = 8 $
✔ Answer: 8
---
Problem 7: 1.84 ÷ 0.08
Multiply both by 100:
- $ 1.84 × 100 = 184 $
- $ 0.08 × 100 = 8 $
Now divide:
- $ 184 ÷ 8 = 23 $
✔ Answer: 23
---
Problem 8: 1.00 ÷ 0.05
Multiply both by 100:
- $ 1.00 × 100 = 100 $
- $ 0.05 × 100 = 5 $
Now divide:
- $ 100 ÷ 5 = 20 $
✔ Answer: 20

✔ Final Answers:
1) 41
2) 5
3) 22
4) 75
5) 4
6) 8
7) 23
8) 20

🔍 Tip:
When dividing decimals,
move the decimal point in the divisor to make it a whole number, then move the decimal point in the dividend the same number of places. Then divide as usual.
This method ensures you are not changing the value of the division — just making it easier to compute!
