Noah made 1 1/2 dozen blueberry muffins and 1 3/4 dozen lemon muffins. He needs to take 5 dozen muffins to the bake sale. How many dozen more muffins does he need to bake?

Respuesta :

1 1/2 + 1 2/4 +1/4 + x= 5     combine like terms 
3 1/4 +x= 5                           subtract 3 1/4 from both sides(3.25 also)
x=1.75 also known as 13/4
so Noha would have to make 1 and 3/4 dozen of muffins to make 5 dozen
