Question

Explain how finding 7x20 is similar to finding 7x2,000. then find each product

Answer 1

These two equations are the same in solving, with this difference that after you compute 7*2=14 you put 1 zero or 3 zero in front of 14.

7*2,0=14,0
7*2,000=14,000 

Answer 2

Answer:

$7\times 20=140$

$7\times 2000=14000$

Step-by-step explanation:

To find : Explain how finding $7\times 20$ is similar to finding $7\times 2,000$ then find both products ?

Solution :

First we find the product of $7\times 20$

$7\times 20=140$ .....(1)

Now, to find the product of $7\times 2,000$

We can re-write the product as,

$7\times 2,000=7\times 20\times 100$

Using (1),

$7\times 2,000=140\times 100$

$7\times 2,000=14000$

It is similar as the difference is about the multiple of 10.
