Final answer:
The probability of pulling out an apple from the bag is 1/4 in reduced fraction form, 0.25 in decimal form, and 25% as a percent.
Step-by-step explanation:
The question asks for the probability of pulling out an apple from a bag containing 5 apples, 10 oranges, and 5 peaches. The total number of fruits in the bag is 5 + 10 + 5 = 20. The probability of pulling out an apple is the number of apples divided by the total number of fruits.
The reduced fraction for the probability is 5/20, which simplifies to 1/4. In decimal form, this probability is 0.25. To express this probability as a percent, multiply the decimal by 100, which gives 25%.
