Question

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

Answer 1

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.

Answer 2

7×20=140

7×2,000=14000

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
