Mario was visiting the carnival when he noticed a few number relationships.
He made then into brainteasers for you.

a. If three-tenths of the visitors were adults and there were 100 visitors, how many visitors were adults?

b. Five-eighths of the prizes at the Giant Spin were dolls. If there were 64 prizes, how many prizes were NOT dolls?

100/1 x3/10=30 adults

B. 5/8 x64/1 =40 dolls

therefore 64-40=24 were not dolls

Answer: a) 30 and b) 24.

Step-by-step explanation:

Since we have given that

a) Number of visitors = 100

According to question, we get that If three-tenths of the visitors were adults.

So, number of adults would be

[tex]\dfrac{3}{10}\times 100\\\\=3\times 10\\\\=30[/tex]

b) Number of prizes = 64

According to question, Five-eighths of the prizes at the Giant Spin were dolls.

So, Number of prizes are not dolls is given by

[tex](1-\dfrac{5}{8})\times 64\\\\=\dfrac{3}{8}\times 64\\\\=3\times 8\\\\=24[/tex]

Hence, a) 30 and b) 24.
