Answer 1

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!

No, he is incorrect.

Explanation:

Given : Your friend thinks that
