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.
