1)  

 Is -304 ÷ 19 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:

-304 is negative. 19 is positive. Use the rule:

negative ÷ positive = negative


So, -304 ÷ 19 is negative.

Now check your answer by doing the maths.

-304 ÷ 19 = -16


Yes, the answer is negative.



2)  

 Is -864 ÷ 27 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:

-864 is negative. 27 is positive. Use the rule:

negative ÷ positive = negative


So, -864 ÷ 27 is negative.

Now check your answer by doing the maths.

-864 ÷ 27 = -32


Yes, the answer is negative.



3)  

Is -8 × -80 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:

-8 is negative. -80 is negative. Use the rule:

negative × negative = positive

So, -8 × -80 is positive.

 

Now check your answer by doing the maths.

-8 × -80 = 640

Yes, the answer is positive.

 



4)  

 Is 784 ÷ 49 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:

 784 is positive. 49 is positive. Use the rule:

 positive ÷ positive = positive

So, 784 ÷ 49 is positive.

Now check your answer by doing the maths.

784 ÷ 49 = 16

Yes, the answer is positive.

 



5)  

 Is -572 ÷ 44 positive or negative



Answer: 2


SOLUTION 1 :

Remember:

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