Answer:
60% = 9 arrows did not the target
Explanation:
Total number of arrows = 15
Percentage of arrows that hit the target = 40%
Number of arrows that hit the target = 40/100 * 15
= 6
Percentage of arrows that did not hit the target = 60%
Number of arrows that did not hit the target = 60/100 * 15
= 9
So, the number of arrows that did not hit the target is 9 arrows.
