Question

you are baking 144 cupcakes for a class party tomorrow you know that you can make 12 cupcakes every 30 minutes how long will it take to bake all the cupcakes

Answer 1

360 minutes because 12 times 12= 144 and you'd multiply 30 by 12 because you'd bake 12 cupcakes every 30 minutes.

Answer 2

Set up a proportion.

12 cupcakes/ 0.5 hrs= 144 cupcakes/ x hrs

12*12=144
0.5*12=6=x

Final answer: 6 hrs
