One cake feeds 14 people. Use a proportion to find how many cakes must be purchased to feed 60 people.
katrin2010 [14]

Answer:

5 cakes


hope it helps

Step-by-step explanation:

if one cake feed 14 people and you are tying to fine out how many cakes you need to feed 60 people you would have to divide 60 by 14

1 cake = 14 people

? cakes = 60 people

60 ÷ 14 = 4.28

so in order to have enough for 60 people you need to round so you would need 5 cakes

to check you answer you can multiply 5 by 14 and you answer should be the amount of people

5 x 14 = 70

why  cant it be 4? well because if you buy 4 cakes there wont be enough for 60 people and to make sure it wont be enough you can multiply 4 x 14

4 x 14 = 56

so 4 cakes only feeds 56 people so that is why your answer is 5 cakes are needed
