Question

Arthur baked 1 7/12 dozen muffins. Nina baked 1 1/12 dozen muffins. How many dozen muffins did they bake?

Answer 1

they baked 2 dozen because each dozen is 12  so one did 17 + another did 11 = 28 and divide it by 12 get. 2 dozens.

Answer 2

Answer:

Total number of dozen muffins they both bake is $2\frac{8}{12}$    

Step-by-step explanation:

Given : Arthur baked $1\frac{7}{12}$ dozen muffins. Nina baked $1\frac{1}{12}$ dozen muffins.

We have to find the total number of dozen muffins did they both bake.

To find the total number of dozen muffins did they both bake is equal to number of dozen of muffins Arthur bake and  number of dozen of muffins Nina bake

That is

Mathematically written as ,

Total number of dozen muffins = number of dozen of muffins Arthur bake + number of dozen of muffins Nina bake

Given : Arthur baked $1\frac{7}{12}$ dozen muffins

and Nina baked $1\frac{1}{12}$ dozen muffins.

Total number of dozen muffins = $1\frac{7}{12}+1\frac{1}{12}$  

Simplify, we get,

Total number of dozen muffins = $1\frac{19}{12}+\frac{13}{12}$  

Adding, we get,

Total number of dozen muffins = $1\frac{19+13}{12}=\frac{32}{12}$  

Thus, Total number of dozen muffins they both bake is $2\frac{8}{12}$
