Answer:14 balls did not hit the target.
Step-by-step explanation:
Since 30% did, you would have to do 70% of 20.
Answer: 14
Step-by-step explanation:
70% of balls did not hit the target, so multiply the number of footballs he threw by 70, then divide by 100 to find how many did not hit the target.
20 x 70 = 1400
1400 / 100 = 14
14 balls did not hit the target
