Let's solve each of these division problems step by step. The goal is to
find the missing divisor (the number we divide by) so that the division equation is correct.
We can use the formula:
>
Dividend ÷ Divisor = Quotient
So, rearranging:
>
Divisor = Dividend ÷ Quotient
We'll apply this for each problem.

📌 Pattern Tip:
Notice that dividing by
10,
100, or
1000 moves the decimal point left:
- Divide by 10 → move decimal
1 place left
- Divide by 100 → move decimal
2 places left
- Divide by 1000 → move decimal
3 places left
For example:
- $ 0.4 \div 10 = 0.04 $ → decimal moved 1 place left ✔️
- $ 5 \div 100 = 0.05 $ → 5 → 0.05 ✔️
This pattern helps check answers quickly!
