By unitary method we can say that number of stacks of papers Lashona will pass back from 140 if each stack conatins 28 papers is 5.
According to the given question.
Total number of papers Lashonna passed back = 140
And one stack is made up of 28 papers.
As we know that, the unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Therefore,
By unitary method number of stacks of papers would be made from 140 if each stack conatins 28 papers
= 140/28
= 5
Hence, by unitary method we can say that number of stacks of papers Lashona will pass back from 140 if each stack conatins 28 papers is 5.
