teaspoons.

Step-by-step explanation:

We have been given that a recipe calls for teaspoons of cinnamon to make 2 dozen oatmeal cookies.

First of all, we will find number of teaspoons needed to make one oatmeal cookies.

1 dozen = 12

2 dozens = 24

Convert mixed fraction into improper fraction:

Convert to division problem by flipping the second fraction as:

Now, we will multiply amount needed for one cookie by 60 to find amount needed to make 60 cookies as:

Therefore, teaspoons are needed to make 60 oatmeal cookies.

From the question:

1 1/2 teaspoons of cinnamon =  2 dozen oatmeal cookies

1 dozen = 12

2 dozen oatmeal cookies = 2 x 12

= 24 oatmeal cookies

Hence:

1 1/2 teaspoons of cinnamon =  24 oatmeal cookies

The number of teaspoons of cinnamon needed to make 60 oatmeal cookies is calculated as:

24 oatmeal cookies = 1 1/2 teaspoons of cinnamon

60 oatmeal cookies =  c

Cross Multiply

24 oatmeal cookies x c = 60 oatmeal cookies x 1 1/2 teaspoons of cinnamon

c =  60 oatmeal cookies x 1 1/2 teaspoons of cinnamon/ 24 oatmeal cookies

x = 3 3/5 teaspoons of cinnamon

Therefore, the number of teaspoons of cinnamon  needed to make 60 oatmeal cookies is 3 3/5 teaspoons of cinnamon
