Question

Se vamos repartir uma barra de chocolate para 4 pessoas, de modo que a primeira receba 1/3 da barra, a segunda 1/4 e a terceira 1/5, então quanto a quarta pessoa receberá?

Answer 1

Answer: The fourth person will receive
`(13)/(60)` of a bar.

Explanation:

Total people = 4

Fraction of chocolate received by first person =
`\frac13`

Fraction of chocolate received by second person =
`\frac14`

Fraction of chocolate received by third person =
`\frac15`

Now, Fraction of chocolate received by fourth person =
`1-(\frac13+\frac14+\frac15)`

`=1-((20+15+12)/(60))\\\\=1-((47)/(60))\\\\=(60-47)/(60)\\\\=(13)/(60)`

So, the fourth person will receive
`(13)/(60)` of a bar.
