Question

Explain how finding 7×20 is similar to finding 7×2,000 then find each product

Answer 1

Answer:

7×20=140

7×2,000=14000

Step-by-step explanation:

The only thing that changes the product of these numbers is the number of zeros behind the 2.

The number of zeros behind  2 affects how many zeros will be included in the product.

7×2=14

i.e. 7×20=7×2×10

             =14×10

             =140

7×2,000=7×2×1000

             =14×1000

             =14000

Answer 2

7x20=140. 7x2000=14000. The only thing that changes the product of these numbers is the amount of zeros behind the 2. Since the only two numbers that affect the answer is the 7 and the 2. (7x2=14). The number of zeros behind the 2 affect how many zeros will be included in the product.
