Answer :
Final answer:
Mark got 75% correct on his spelling test, by dividing the number of correct answers (15) by the total questions (20) and converting to a percentage.
Explanation:
To find what percent Mark got correct, you divide the number of questions he got right (15) by the total number of questions (20), and then multiply the result by 100 to get a percentage.
Step 1: Divide 15 by 20: 15 ÷ 20 = 0.75.
Step 2: Multiply by 100 to convert to a percentage: 0.75 * 100 = 75%.
Therefore, Mark got a 75% on his spelling test, showing a good performance in spelling accuracy.
