Question

Find the product of 27×60 then explain how you would use mental math to find the product of 27×600

Answer 1

27x6
162

27x60
1620

27x600=
16200

the product will be 16200 because 60x10 is equal to 600
27x60 is 1620 you also multiply it by 10

Answer 2

`27* 60=1620`

`27* 600=16200`

Explanation:

We are asked to find the product of
`27* 60` and then product of
`27* 600`.

`27* 60=1620`

We can use this result to find the product of
`27* 600`. We can see that in product of
`27* 60`, there is one zero after 6. In product of
`27* 600`, there are two zero after 6.

We can represent the second product as:

`27* 60* 10`

Substitute result from 1st product as:

`1620* 10`

`16200`

Therefore, the product of
`27* 600` would be 10 times more than product of
`27* 60`.
