An integer is a whole number without decimals or fractions
Not all decimals can be expressed as fractions. Only terminating and recurring decimals can be expressed as fractions. eg a recurring decimal: 0.3333333... = 1/3 A terminating decimal: 0.125 = 1/8 A decimal that does not recurr or terminate, cannot be expressed as a fraction. eg Pi = 3.141592654... Pi can not be expressed as a fraction as it does not recurr or terminate. It can only be approximated to a fraction. eg Pi ≈ 355/113 but is correct to 6 decimal places.
Whether fractions work better than decimals or less as well is very much a question of your preference.
There are no 'equivalent decimals' to decimal numbers. But if you express 0.6 as a fraction, there are an infinite number of equivalent fractions. 0.6 is 6/10. This is equivalent to 3/5, 12/20, 24/40, 6,000/10,000 etc.

The Arabs wished to express quantities that were not whole numbers. As to why they used fractions as opposed to decimals for this, that was owing to the fact that they had not invented decimals yet.

They Are both ways to express partial #'s
It is: 3/10 expressed as a decimal is 0.3
fraction and decimals are both have similarities because they both express part of a whole.

eighty one hundredths = 0.81 in decimals
The fraction 1/3=0.3333333... In this case it is better to use fractions just like in all cases. There will be no case when decimals will work better than fractions however, if a test says to use decimals; USE THEM!
As long as you are expressing those fractions in tenths, yes.
