Answer:
Nearly 83.33%
Step-by-step explanation:
There are 12 pairs of cranial nerves connected in the brain.
10 of these pairs are related to the site, smell, taste, and sound.
So,
12 - 100%
10 - x%
Write a proportion:
[tex]\dfrac{12}{10}=\dfrac{100}{x}[/tex]
Cross multiply
[tex]12\cdot x=10\cdot 100\\ \\12x=1,000[/tex]
Divide by 12:
[tex]x=\dfrac{1,000}{12}=\dfrac{250}{3}\approx 83.33\%[/tex]
