Karen bought cupcakes for her sister's birthday party. 3 cupcakes had sprinkles on top. The other 27 cupcakes did not have sprin
kles. What percentage of the cupcakes had sprinkles?
1 answer:
Answer:
10%
Step-by-step explanation:
so
3 cupcakes had sprinkles
27 didn't have sprinkles
which means that there are a total of 30 cupcakes, (because 3 + 27 is 30)
so then set up a proportion
part/whole = percent/one hundred
substitute in the given values
3 / 30= precent/100
simplify
1/10 = precent/100
you don't have to use cross products here because it is pretty obvious that 10 * 10 = 100 so then just multiply 1/10 by 10 and you get your answer
percent = 10
