Respuesta :

Your friend is incorrect.
You should always count 0's when deciding where to place the decimal point. To disprove your friend, you could divide 1.2 by 8 and see that it doesnt equal 1.5. Also, 8 is multiplied by a value that is more than one, so the result should be higher than 8.

Good luck with your assignment!

Answer:

No, he is incorrect.

Step-by-step explanation:

Given : Your friend thinks that [tex]1.5\times 8=1.20[/tex] because you do not count the zero when placing the decimal point.

To find : Is your friend correct justify your reasoning ?

Solution :

Your friend is incorrect.

As we should always count 0's when deciding where to place the decimal point.

Multiplying 1.5 by 8 is

 1.5     - 1 decimal place

×  8      - 0 decimal place

--------

12.0     - 1 total decimal place

So, Friend calculation is not correct as well as explanation.

The correct answer is [tex]1.5\times 8=12.0[/tex]
