Explain the meaning of the term unitary method?

• The unitary approach includes determining the value of an individual unit, from which we can calculate the values of the necessary number of units.
• By using the unitary technique, we may calculate the value of a particular unit from the values of several other units, and then we can use this value to calculate the value of the necessary number of units.

As the stated question-

For 5 small fish -----> 6-gallon fish tank required.

Then, for 1 small fish,

1 small fish -----> 6/5 -gallon fish tank required.

For the total of 40 small fish.

40 small fish -----> 40x6/5 -gallon fish tank required.

40 small fish -----> 48 -gallon fish tank required.

Thus, for containing the 40 small fish, the size of the fish tank required is

48 -gallon.
