| 4) Is 43 × - 25 positive or negative
Answer: 1 SOLUTION 1 : Remember: When 2 integers have the same sign, the product is positive: When 2 integers have different signs, the product is negative: Solve: 43 is positive. - 25 is negative. Use the rule: positive × negative = negative
Now check your answer by doing the maths. 43 × - 25 = - 1075 Yes, the answer is negative. |
| 5) Is -32 ÷ -8 positive or negative
Answer: 2 SOLUTION 1 : Remember: When 2 integers have the same sign, the quotient is positive: When 2 integers have different signs, the quotient is negative: Solve: - 32 is positive. - 8 is positive. Use the rule: positive ÷ positive = positive
Now check your answer by doing the maths. - 32 ÷ - 8 = 4
|
| 6) Is -3 × 35 positive or negative
Answer: 1 SOLUTION 1 : Remember: When 2 integers have the same sign, the product is positive: When 2 integers have different signs, the product is negative: Solve: -3 is negative. 35 is positive. Use the rule: negative × positive = negative
Now check your answer by doing the maths. -3 × 35 = -105
|
| 7) Is 60 ÷ 15 positive or negative
Answer: 1 SOLUTION 1 : Remember: When 2 integers have the same sign, the quotient is positive: When 2 integers have different signs, the quotient is negative: Solve: 60 is positive. 15 is positive. Use the rule: positive ÷ positive = positive
Now check your answer by doing the maths. 60 ÷ 15 = 4
|
| 8) Is 47 × - 70 positive or negative
Answer: 1 SOLUTION 1 : Remember: When 2 integers have the same sign, the product is positive: When 2 integers have different signs, the product is negative: Solve: 47 is positive. - 70 is negative. Use the rule: positive × negative = negative
Now check your answer by doing the maths. 47 × - 70 = - 3290 Yes, the answer is negative. |
