Which strategies can be used to find the product of 629 x 100? Check all that apply.
moving the digits of 629 three places to the left
multiplying (600 + 20 + 9) x 100
putting 2 zeros on the end of 629
moving the digits of 629 two places to the right
multiplying (6,000 + 200 +90) x 10

Answer :

Answer:

The strategies (2), (3) and (5) can be applied.

Step-by-step explanation:

In this case we need to compute the product of 629 × 100.

The product can be found in the following ways:

  • multiplying (600 + 20 + 9) x 100

       [tex](600 + 20 + 9) \times 100=(600\times 100)+(20\times 100)+(9\times 100)\\=60000+2000+900\\=62900[/tex]

  • putting 2 zeros on the end of 629

        [tex]629\times 100=62900[/tex]

  • multiplying (6,000 + 200 +90) x 10

       [tex](6000 + 200 + 90) \times 10=(6000\times 10)+(200\times 10)+(90\times 10)\\=60000+2000+900\\=62900[/tex]

Thus, the strategies (2), (3) and (5) can be applied.
