Question

In words, explain why the "add a decimal and zero" "rule" works.

Answer 1

Answer:

In words explain why the “add a decimal and zero” “rule” works.

You should be able to explain the rule works because it shows the whole number

equivalent to the tenths. Therefore you are dividing tenths and not wholes.

In words explain how to convert 4/9 to a decimal.

4 wholes are exchanged for 40 tenths and represented as 4.0. 4 tenths are in each group and 4

tenths are left over. The 4 tenths are exchanged for 40 hundredths and 4 hundredths are in

each group. This pattern will continue resulting in a repeating decimal.

HOPE THIS HELPS!!

Answer 2

Basically it's just so you can divide all the way without having to put in a remainder, and putting in the decimal where it belongs.
