Question

Anthony's birthday, his mother is making cupcakes for his 12 friends at his daycare. the recipe calls for 3 cups of flour. this recipe makes 2 1/2 dozen cupcakes. anthony's mother has only 1 cup of flour. is there enough flour for each of his friends to get a cupcake? k

Answer 1

You would need to set up a proportion to solve. 
3/30=1/x
Cross multiply: 3x=30, so x=10
It would not be enough flour for each friend to get a cupcake.
