Find the number that has been multiplied by 100

We are given results of multiplication by 100, so we divide by 100 to get original number.

#### 1. $ \_\_ \times 100 = 361,100 $
- $ 361,100 ÷ 100 = 3,611 $

#### 2. $ \_\_ \times 100 = 861,300 $
- $ 861,300 ÷ 100 = 8,613 $

#### 3. $ \_\_ \times 100 = 656,300 $
- $ 656,300 ÷ 100 = 6,563 $

#### 4. $ \_\_ \times 100 = 521,200 $
- $ 521,200 ÷ 100 = 5,212 $

#### 5. $ \_\_ \times 100 = 861,500 $
- $ 861,500 ÷ 100 = 8,615 $

#### 6. $ \_\_ \times 100 = 819,100 $
- $ 819,100 ÷ 100 = 8,191 $

#### 7. $ \_\_ \times 100 = 521,000 $
- $ 521,000 ÷ 100 = 5,210 $

#### 8. $ \_\_ \times 100 = 517,000 $
- $ 517,000 ÷ 100 = 5,170 $

Find the number that has been multiplied by 1,000

We divide by 1,000 to reverse the operation.

#### 1. $ \_\_ \times 1,000 = 164,000 $
- $ 164,000 ÷ 1,000 = 164 $

#### 2. $ \_\_ \times 1,000 = 5,121,000 $
- $ 5,121,000 ÷ 1,000 = 5,121 $

🔍 Explanation

- Multiplying by 10: Add one zero or move decimal one place right.
- Multiplying by 100: Add two zeros or move decimal two places right.
- Multiplying by 1,000: Add three zeros or move decimal three places right.
- Dividing by 10, 100, 1,000: Reverse process — move decimal left.

This pattern works because our number system is base-10.
