Final answer:
Riley made 18 free throws. To calculate this, convert 10% to a decimal (0.10) and multiply by the total shots (180), resulting in 18 successful free throws.
Step-by-step explanation:
Riley made 10% of her free throws over the season. To find out how many free throws she made, we need to calculate 10% of the total number of free throws she shot, which was 180. To do this, you can set up a simple multiplication:
Number of free throws made = 10% of 180
Convert the percentage to a decimal by dividing by 100:
10% = 0.10
Now multiply the decimal by the total number of shots:
0.10 × 180 = 18
Therefore, Riley made 18 free throws.
The correct answer is option b) 18 free throws.
