Out of attempts, a basketball player scored times. What percent of his attempts did he score?
A
× = 25%
B
× = 80%
C
× = 60%
D
× = 40%
Verified step by step guidance1
Identify the total number of attempts and the number of successful scores. Here, the player attempted 20 shots and scored 8 times.
Write the fraction representing the successful attempts over total attempts as \(\frac{8}{20}\).
To find the percentage of successful attempts, multiply the fraction by 100: \(\frac{8}{20} \times 100\).
Simplify the fraction \(\frac{8}{20}\) by dividing numerator and denominator by their greatest common divisor.
Calculate the product of the simplified fraction and 100 to get the percentage of successful attempts.
