While working on fractions, a student of class V, does the question as follows:
\(\dfrac{2}{3} - \dfrac{1}{3}=\dfrac{1}{0}\)
As a teacher, which one of the following strategies would be most appropriate to follow?
1
explain the error by using a fraction kit or paper folding
2
ask the student to do the same question 10 times so that he/she will not repeat the mistake
3
tell the algorithm for subtraction of fractions
4
give more questions for practice
