Final answer:
The correct answers to the question about the fraction and percentage of times the baseball player did not get a hit are 31/100 and 31%.
Step-by-step explanation:
If a baseball player got 69 hits out of 100 at-bats, the number of times the player did not get a hit is 100 at-bats minus 69 hits, which equals 31 at-bats where the player did not get a hit. To find the fraction, we simply put the number of unsuccessful at-bats over the total number of at-bats, which results in 31/100. To find the percentage, we convert this fraction to a percentage by multiplying by 100, giving us 31%. Thus, the correct answers are A) 31/100, 31%.
