F. Arman dribbled the ball 18 times. How many more times should he dribble the ball to complete 35 taps?
Given: Total taps needed = 35 Arman already dribbled = 18 times
Solution: To find how many more times Arman needs to dribble, we subtract what he has already done from the total needed.
Calculation: 35 - 18 = 17
With borrowing: Since 5 < 8, borrow 1 ten from 3 Now we have 15 ones and 2 tens Subtract ones: 15 - 8 = 7 Subtract tens: 2 - 1 = 1
Answer: Arman should dribble the ball 17 more times.
Explanation
To find how many more times Arman needs to dribble, we subtract what he has already done from the total needed. 35 - 18 = 17. With borrowing: Since 5 < 8, borrow 1 ten. 15 - 8 = 7, and 2 - 1 = 1. Answer = 17.
Solution Steps
Step 1: Total taps needed = 35
Step 2: Arman already dribbled = 18 times
Step 3: Since 5 < 8, borrow 1 ten from 3
Step 4: Now we have 15 ones and 2 tens
Step 5: Subtract ones: 15 - 8 = 7
Step 6: Subtract tens: 2 - 1 = 1
Step 7: Answer = 17 more dribbles
