Christopher made 3 1/4 dozen cupcakes. he added vanilla icing to 1/3 of the cupcakes and added chocolate icing to the rest. how many cupcakes, in dozens, have chocolate icing?

1 dozen = 12

First you would multiply.

3.25 x 12 = 39 cupcakes total
1/3 x 12 = 4 cupcakes with vanilla icing

Then you subtract.

39 - 4 = 35 cupcakes with chocolate icing

Then to get the answer back in to terms of dozens, divide by 12.

35/12 = 2 11/12

Hope this helped

A dozen is 12 so 3 and 1/4 dozen would be 39 cupcakes
1/3 of 39 is 13 
39 - 13 is 26 
so, 26 cupcakes would have chocolate icing which would be 2 1/6 dozen 

Yo no me sé esa mala mia

7p=14 so then you would divide by p=2
