No, it is not.
It is not always helpful.Some people may find it helpful when comparing fractions. By converting them into percentages they are made into like fractions: all with the denominator 100.
You can learn more about converting decimals into fractions by taking math classes. You can also learn more about converting decimals into fractions on various websites like MathisFun and WebMath.
by converting them to equivalent fractions
it depends on what you're converting. fractions to decimals, decimals to fractions, etc. there are so many different ways. what are you converting? then maybe i can help
A math teacher or a mathematician.
You basically have to learn separately how to do different things with fractions, including finding a common denominator; converting fractions to a different denominator; simplifying fractions; adding and subtracting fractions; multiplying fractions; dividing fractions.
This can be especially helpful if you are adding or subtracting fractions, so the bottom number on both fractions will be the same
