6[tex]\frac{3}{4}[/tex] teaspoons of baking powder will be needed to make 3 dozen muffins.
The unitary method is a method in which you find the value of a unit and then the value of a required number of units.
In the unitary method, the value of a unit quantity is calculated first to calculate the value of other units. It has two types of variations.
We can use the unitary method to solve the given question.
It is given that for 8 muffins 1[tex]\frac{1}{2}[/tex] teaspoons of baking powder is required.
And we need to find the amount of baking powder for 3 dozen muffins.
3 dozen= 3×12 because 1 dozen has 12 muffins
= 36 muffins
Now,
1[tex]\frac{1}{2}[/tex] or 1.5 teaspoon for 8 muffins
Then how many teaspoons for 36 muffins
So,
1.5×[tex]\frac{36}{8}[/tex]
= [tex]\frac{54}{8}[/tex]
=6.75
=6[tex]\frac{3}{4}[/tex] teaspoons
So 6[tex]\frac{3}{4}[/tex] teaspoons are required.
