Out of 30 kids that came to a Halloween party 4 wore Harry Potter costumes, 3 were dressed as Ron Weasley, and 5 were dressed as Hermione Granger. What percent of all kids at the party were dressed as Hogwarts students?
That's wrong
How?
fraction = 12/30 = 2/5 or .4 or 40%
If "they" don't accept that answer, which Barry Vacker also had, then there is either
a misprint in the question, or an error in the answer key.
To find the percent of kids dressed as Hogwarts students, we first need to determine the total number of kids dressed as Hogwarts students. In this case, the Hogwarts students include those dressed as Harry Potter, Ron Weasley, and Hermione Granger.
To get this number, we add up the number of kids dressed as each character:
4 (Harry Potter) + 3 (Ron Weasley) + 5 (Hermione Granger) = 12
Therefore, there were 12 kids dressed as Hogwarts students.
Next, we need to calculate the percentage. To do this, we divide the number of kids dressed as Hogwarts students by the total number of kids at the party (which is 30).
(12 / 30) * 100 = 40
So, 40% of all kids at the party were dressed as Hogwarts students.
Add: 4 + 3 + 5 = ?
?/30 = (simplify that to lowest terms)
Answer: ?/5
