Emma’s fraction of the mangoes cannot be uniquely determined from the phrase “what fraction of mangoes did Emma get” alone; it depends on extra details that are not specified in your prompt.

Core idea

To know what fraction of mangoes Emma got , you must know at least:

  • The total number of mangoes (call this TTT).
  • How many of those Emma received (call this EEE).

Then the fraction is simply:

Fraction Emma got=ET\text{Fraction Emma got}=\frac{E}{T}Fraction Emma got=TE​

Why many online answers differ

Different sites attach different background stories to the same question:

  • Some treat it as a data-sufficiency puzzle with statements like “There are five people” and “Everyone got an equal number of mangoes,” from which one can say Emma received 15\tfrac{1}{5}51​ of the mangoes if she is one of the five and all share equally.
  • Others argue that even those two statements are not enough, and regard the information as insufficient, focusing on exam-style logic rather than the arithmetic.
  • Another example scenario uses “Emma got 5 out of 20 mangoes,” in which case her fraction would be 520=14\tfrac{5}{20}=\tfrac{1}{4}205​=41​.

Because your post only gives the bare title and no story (like “5 people shared the mangoes equally” or “Emma got 5 out of 20”), there is no single correct numerical fraction that can be stated.

If your original problem was this common variant

If your textbook/worksheet said something like:

“There are five people among whom mangoes have been distributed. Everyone has got an equal number of mangoes. What fraction of mangoes did Emma get?”

and Emma is one of the five, then:

  • Total people = 5
  • All share equally ⇒ each gets the same fraction ⇒ Emma’s fraction is

15\frac{1}{5}51​

So:

  • If the problem explicitly mentions “5 people, equally shared,” answer: Emma got 15\tfrac{1}{5}51​ of the mangoes.
  • If not, the question is incomplete, and you should ask for the missing information (total mangoes or the sharing rule).

TL;DR: With only the title “what fraction of mangoes did Emma get,” the fraction cannot be fixed; you need the specific numbers or sharing rule. If it’s the usual “5 people share equally” puzzle, then Emma’s share is 15\tfrac{1}{5}51​.
