Question
Ava and William do maths practice questions every day. One day, Ava answered 60% of the questions correctly while William answered 45% of them correctly. How much better did Ava perform than William?Express your answer as a percentage of William's score, rounded to the nearest whole number.
Solution
To solve this problem, we need to find out how much better Ava performed than William in terms of percentage.
Here are the steps:
-
First, we need to find the difference in their performance. Ava answered 60% of the questions correctly and William answered 45% correctly. So, the difference is 60% - 45% = 15%.
-
Next, we need to express this difference as a percentage of William's score. To do this, we divide the difference by William's score and then multiply by 100.
So, the calculation is (15 / 45) * 100 = 33.33%.
- Finally, we round this to the nearest whole number. So, Ava performed 33% better than William.
