1)  

Is -3 × -60 positive or negative



Answer: 1


SOLUTION 1 :

Remember:

When 2 integers have the same sign, the product is positive:
positive × positive = positive
negative × negative = positive

When 2 integers have different signs, the product is negative:
positive × negative = negative
negative × positive = negative

Solve:

-3 is negative. -60 is negative. Use the rule:

negative × negative = positive

So, -3 × -60 is positive.

 

Now check your answer by doing the maths.

-3 × -60 = 180

Yes, the answer is positive.

 



2)  

 Is -391 ÷ 23 positive or negative



Answer: 1


SOLUTION 1 :

Remember:

When 2 integers have the same sign, the quotient is positive:
positive ÷ positive = positive
negative ÷ negative = positive

When 2 integers have different signs, the quotient is negative:
positive ÷ negative = negative
negative ÷ positive = negative

Solve:

-391 is negative. 23 is positive. Use the rule:

negative ÷ positive = negative


So, -391 ÷ 23 is negative.

Now check your answer by doing the maths.

-391 ÷ 23 = -17


Yes, the answer is negative.



3)  

 Is -704 ÷ 22 positive or negative



Answer: 2


SOLUTION 1 :

Remember:

When 2 integers have the same sign, the quotient is positive:
positive ÷ positive = positive
negative ÷ negative = positive

When 2 integers have different signs, the quotient is negative:
positive ÷ negative = negative
negative ÷ positive = negative

Solve:

-704 is negative. 22 is positive. Use the rule:

negative ÷ positive = negative


So, -704 ÷ 22 is negative.

Now check your answer by doing the maths.

-704 ÷ 22 = -32


Yes, the answer is negative.



4)  

 Is 800 ÷ 16 positive or negative



Answer: 1


SOLUTION 1 :

Remember:

When 2 integers have the same sign, the quotient is positive:
positive ÷ positive = positive
negative ÷ negative = positive

When 2 integers have different signs, the quotient is negative:
positive ÷ negative = negative
negative ÷ positive = negative

Solve:

 800 is positive. 16 is positive. Use the rule:

 positive ÷ positive = positive

So, 800 ÷ 16 is positive.

Now check your answer by doing the maths.

800 ÷ 16 = 50

Yes, the answer is positive.

 



5)  

Is -5 × -40 positive or negative



Answer: 2


SOLUTION 1 :

Remember:

When 2 integers have the same sign, the product is positive:
positive × positive = positive
negative × negative = positive

When 2 integers have different signs, the product is negative:
positive × negative = negative
negative × positive = negative

Solve:

-5 is negative. -40 is negative. Use the rule:

negative × negative = positive

So, -5 × -40 is positive.

 

Now check your answer by doing the maths.

-5 × -40 = 200

Yes, the answer is positive.

 



6)  

 Is -608 ÷ 19 positive or negative



Answer: 2


SOLUTION 1 :

Remember:

When 2 integers have the same sign, the quotient is positive:
positive ÷ positive = positive
negative ÷ negative = positive

When 2 integers have different signs, the quotient is negative:
positive ÷ negative = negative
negative ÷ positive = negative

Solve:

-608 is negative. 19 is positive. Use the rule:

negative ÷ positive = negative


So, -608 ÷ 19 is negative.
