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

`7* 20=140`

`7* 2000=14000`

Explanation:

To find : Explain how finding
`7* 20` is similar to finding
`7* 2,000` then find both products ?

Solution :

First we find the product of
`7* 20`

`7* 20=140` .....(1)

Now, to find the product of
`7* 2,000`

We can re-write the product as,

`7* 2,000=7* 20* 100`

Using (1),

`7* 2,000=140* 100`

`7* 2,000=14000`

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