66.7%

667/1000

Explanation:

It is easier to do it the other way round in that you derive the fraction first.

For decimals you have in order of unit size:

"decimal point "1/10+1/100+1/1000

So for the decimal given we have:

6/10+6/100+7/1000

This can be written as: 667/1000
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To convert this to the non fraction form of percentage we do this:

667/1000 xx100 = 66.7%

Expressed as a percent fraction this is (66.7)/100

But we do not like decimal values as a numerator so we are back to

(66.7xx10)/(100xx10)=667/1000
