Write 8.42 repeating as a mixed number in simplest form

In this number, we separate the whole number from the items or digits that come after the decimal point. With that, we have,
              8 and 0.42
The repeating digits after the decimal point is converted to a fraction form by dividing the number by 9 for each repeating digit. 

In this item, we take that 0.42 is repeating such that the simplest form would be,
                  42/99
Simplifying will give us an answer of 14/33

Hence, the mixed form of the number is 8 14/33.
