    What is a unitary method?

    A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
    Given, Nathan practices the piano for 1260 minutes in 3 weeks.
    ∴ No. of minutes he practiced the piano each day is the total minutes divided by the total no. of days which is,
    = (1260/3) minutes.
    = 420 minutes.
