Eduardwww [97]

Answer:

The remaining child got a fraction of  \frac{1}{10}.

Step-by-step explanation:

Lets take the fraction of the money fourth child got is x

Addition of all these fractions should be equal to 1.

⇒\frac{1}{3} +\frac{1}{6} +\frac{2}{5} +x=1

⇒\frac{10+5+12+30x}{30} =1 (Taking a common denominator)

⇒\frac{27+30x}{30} =1

⇒x=0.1

Therefore,

The remaining child got a fraction of  \frac{1}{10}.
