How do you know the power of 10 by which to multiply a divisor and a dividend when dividing by a decimal. plz send lol

Easy if you understand what is going on.

Step-by-step explanation:

I hope I understand you question correctly.

0.6 means 6/10

Please see 0.6 as 0.6 /1

Now in this case you see the numerator is 0.6

and the denominator is 1.

To get rid of the 0.6 you multiply the numerator by 10.

But if you do that, you also need to multiply the denominator by that same amount !

Hence 6/10.

0.125 means 125/1000

To get rid of the 0.125 you multiply the numerator by 1000

But if you do that, you also need to multiply the denominator by that same amount !

Hence 125/1000 (which is the same 1/8 by the way).

Easy if you understand what is going on.

Is this what you wanted to know?
