Because that it s harder to work out percentages than fractions and decimals
They can both be converted into decimals and from there into fractions or percentages.
Fractions can be converted to decimals, percentages or mixed numbers.
They're all numbers.
Decimals and percentages are easier to compare than fractions - particularly if they are unlike fractions. That does not explain why percentages are required when we have decimal number and there is no good answer to that!

They are ways of calculating and comparing parts of wholes.
If we didn't have decimals, fractions and percentages math would be impossible. Try answering 1.7 - 0.6 without a decimal, and get the right answer. It has not made math easier or harder, it is an element we need.
convert them to decimals or percentages first to figure out the order then write the answers as fractions
