Solution:
As the two numbers [tex]15 \frac{1}{3} {\text{and} -4\frac{2}{3}[/tex] are mixed fractions.
[tex]15 \frac{1}{3}= \frac{46}{3} \\\\ -4\frac{2}{3}= \frac{-14}{3}[/tex]
Now, [tex]\frac{ \frac{46}{3}}{\frac{-14}{3}}[/tex] = - 3
Ankur's answer= 3
The mistake he has committed , while dividing two fractions , he must have forgot that one of the fraction which is in the denominator bears negative sign before it.
So, [tex]\frac {+}{-}= -[/tex].
Ankur forgot to put negative sign before 3.
So, The correct option which describes ankur's error is : Ankur found that the quotient of a positive number and a negative number is positive.
Option 3 is right choice.
