The required answer to the given problem is She did not use the reciprocal of the divisor
The correct option is (b)
What is fraction?
If any number a is divided by b then a/b is called fraction
For example:
2/3 is a fraction, 5/6 in another fraction
How to simplify the fractions?
If we have two fractions say a/b and c/d then the division of these two fractions can be calculated as
[tex]\frac{\frac{a}{b} }{\frac{c}{d} } =\frac{a}{b}\times\frac{d}{c}[/tex]
that is the fraction which is in denominator then its reciprocal will multiply with numerator.
Here we have 5/4 as denominator then She have to multiply with numerator its reciprocal
But She made a mistake and multiplied direct 5/4
Therefore it makes error to the answer
The correct option is (b)
This is the conclusion to the answer.
