There are 2 ways to convert fractions to decimals.
Make an equivalent fraction with a power of 10 as the denominator.
This can only be done with denominators such as:
2, 4, 5, 8, 10, 16, 20, 25, 40, 50 etc., which are factors of 10,100,1,000,10,000and so on.
but not with denominators which are multiples of 3, 7, 11 etc.
so devide 7/6 ;you get =1.1666
