Answer 1

Hint: First, find the number of cups of flour required for making 1 dozen muffins. After that, multiplying the number of cups of flour required for making 1 dozen muffins by 5 to get the number of cups of flour required to make 5 dozen muffins will be the desired result.

Complete step-by-step answer:
According to the question, it is given that 1.5 cups of flour are required for making 3 dozen muffins. It is asked to find the number of cups of flour required to make 5 dozen muffins.
$ \Rightarrow $ 3 dozen muffins require $ = 1.5$ cups of flour
So, the number of cups of flour for making 1 dozen muffins is,
$ \Rightarrow $ 1 dozen muffins require $ = \dfrac{{1.5}}{3}$ cups of flour
Simplify the terms,
$ \Rightarrow $ 1 dozen muffins require $ = 0.5$ cups of flour
Now, the number of cups of flour for making 5 dozen muffins will be the multiplication of 5 with the number of cups of flour for making 1 dozen muffins. So,
$ \Rightarrow $ 5 dozen muffins require $ = 0.5 \times 5$ cups of flour
Multiply the terms,
$ \Rightarrow $ 5 dozen muffins require $ = 2.5$ cups of flour

Hence, the number of cups of flour required to make 5 dozen muffins is 2.5 cups.

Note:
Unitary method is the easiest way of solving this type of arithmetic question where you can get the value of 1 dozen muffins by dividing total muffins by total cups of flour.
