Question

Cesar needs 1 1/2 cups of flour to make a cake that will serve 14 people. If Cesar wants to make enough cake to serve 28 people, how many cups of flour will he need?

2 1/2
2
6
3 1/4

Answer 1

im stuck between 2 and 2 1/2 because it does say 1 1/2 will serve 14 people and 14 + 14=28 meaning adding 1 1/2 + 1 1/2 =2.1

Answer 2

1 1/2=1.5
so answer should be 1.5+1.5=3
but it's not in the answer
i think there is some problem with the answer
