(a) Given, 369 \div \underline{\ \ \ \ \ \ } = 369

A number divided by 1 gives the number itself.

369 \div \underline{1} = 369          

 

(b) (-75) \div \underline{\ \ \ \ \ } = -1

The product is negative, therefore there must be odd number of negative integers. 

(-75) \div \underline{75} = -1
                

(c) (-206) \div \underline{\ \ \ \ }= 1

A number divided by itself gives 1

(-206) \div \underline{(-206)}= 1           

 

(d) (-87) \div \underline{\ \ \ \ }= 87

The product is positive, therefore there must be even number of negative integers. 

(-87) \div \underline{(-1) }= 87
                

(e)\underline{\ \ \ \ } \div 1 = - 87

A number divided by 1 gives the number itself.                

\underline{(-87)} \div 1 = - 87

 

(f) \underline{\ \ \ \ \ } \div 48 = -1

The product is negative, therefore there must be odd number of negative integers. 

\underline{(-48)} \div 48 = -1
                

(g) 20\div \underline{\ \ \ \ \ } = -2

The product is negative, therefore there must be odd number of negative integers. 

20\div \underline{(-10)} = -2               

 

(h) \underline{\ \ \ \ \ } \div (4) = -3

The product is negative, therefore there must be odd number of negative integers. 

\underline{\left (\frac{-4}{3} \right ) } \div (4) = -3
