A number in a fraction implies the part of a number in another given number. While percentage relates a given number to 100%. Thus the answers to the given question are:
a. a fraction of penalty shots that the team missed = [tex]\frac{81}{100}[/tex]
b. percentage of penalty shots missed = [tex]\frac{81}{100}[/tex] x 100%
= 81%
A fraction is a part of a given number stated in a quotient form. Generally, all numbers can be expressed in form of fractions, even whole numbers.
The percentage is an expression that shows the part of a number in a given number with respect to 100%. An example is 10%([tex]\frac{10}{100}[/tex]).
From the given question, let;
n, number of penalty shots made = 19
T, the total number of penalties taken = 100
Thus, the number of penalties missed = T - n
= 100 - 19
= 81
Thus,
i. a fraction of penalty shots that the team missed = [tex]\frac{81}{100}[/tex]
ii. percentage of penalty shots missed = [tex]\frac{81}{100}[/tex] x 100%
= 81%
