Step-by-step solution for: Multiplying and dividing integers worksheet
Problem: Dividing Integers
The task involves solving 16 division problems involving integers. The rules for dividing integers are as follows:
1. Same Signs: When dividing two integers with the same sign (both positive or both negative), the result is positive.
2. Different Signs: When dividing two integers with different signs, the result is negative.
Let's solve each problem step by step.
---
Problem 1: \( (+1075) \div (+43) \)
- Both numbers are positive.
- Perform the division: \( 1075 \div 43 = 25 \).
- Result: \( +25 \).
Answer: \( 25 \)
---
Problem 2: \( (+4165) \div (-85) \)
- The dividend is positive, and the divisor is negative.
- Perform the division: \( 4165 \div 85 = 49 \).
- Since the signs are different, the result is negative.
- Result: \( -49 \).
Answer: \( -49 \)
---
Problem 3: \( (+3400) \div (+34) \)
- Both numbers are positive.
- Perform the division: \( 3400 \div 34 = 100 \).
- Result: \( +100 \).
Answer: \( 100 \)
---
Problem 4: \( (-3007) \div (-97) \)
- Both numbers are negative.
- Perform the division: \( 3007 \div 97 = 31 \).
- Since the signs are the same, the result is positive.
- Result: \( +31 \).
Answer: \( 31 \)
---
Problem 5: \( (-672) \div (+16) \)
- The dividend is negative, and the divisor is positive.
- Perform the division: \( 672 \div 16 = 42 \).
- Since the signs are different, the result is negative.
- Result: \( -42 \).
Answer: \( -42 \)
---
Problem 6: \( (+4418) \div (+47) \)
- Both numbers are positive.
- Perform the division: \( 4418 \div 47 = 94 \).
- Result: \( +94 \).
Answer: \( 94 \)
---
Problem 7: \( (-5135) \div (-65) \)
- Both numbers are negative.
- Perform the division: \( 5135 \div 65 = 79 \).
- Since the signs are the same, the result is positive.
- Result: \( +79 \).
Answer: \( 79 \)
---
Problem 8: \( (+4416) \div (+46) \)
- Both numbers are positive.
- Perform the division: \( 4416 \div 46 = 96 \).
- Result: \( +96 \).
Answer: \( 96 \)
---
Problem 9: \( (+1752) \div (+73) \)
- Both numbers are positive.
- Perform the division: \( 1752 \div 73 = 24 \).
- Result: \( +24 \).
Answer: \( 24 \)
---
Problem 10: \( (-754) \div (+26) \)
- The dividend is negative, and the divisor is positive.
- Perform the division: \( 754 \div 26 = 29 \).
- Since the signs are different, the result is negative.
- Result: \( -29 \).
Answer: \( -29 \)
---
Problem 11: \( (+3420) \div (+57) \)
- Both numbers are positive.
- Perform the division: \( 3420 \div 57 = 60 \).
- Result: \( +60 \).
Answer: \( 60 \)
---
Problem 12: \( (-4980) \div (+83) \)
- The dividend is negative, and the divisor is positive.
- Perform the division: \( 4980 \div 83 = 60 \).
- Since the signs are different, the result is negative.
- Result: \( -60 \).
Answer: \( -60 \)
---
Problem 13: \( (+402) \div (+67) \)
- Both numbers are positive.
- Perform the division: \( 402 \div 67 = 6 \).
- Result: \( +6 \).
Answer: \( 6 \)
---
Problem 14: \( (-2272) \div (+71) \)
- The dividend is negative, and the divisor is positive.
- Perform the division: \( 2272 \div 71 = 32 \).
- Since the signs are different, the result is negative.
- Result: \( -32 \).
Answer: \( -32 \)
---
Problem 15: \( (+4690) \div (+67) \)
- Both numbers are positive.
- Perform the division: \( 4690 \div 67 = 70 \).
- Result: \( +70 \).
Answer: \( 70 \)
---
Problem 16: \( (+3612) \div (+42) \)
- Both numbers are positive.
- Perform the division: \( 3612 \div 42 = 86 \).
- Result: \( +86 \).
Answer: \( 86 \)
