To simplify  : \frac{45}{(-5)} \div \frac{27}{(-9)}

Solution :  

  • According to given question we have to find the value of given expression .
  • To solve the above given expression we take reciprocal of second term by changing the sign of division to multiplication . i.e \frac{45}{(-5 ) }\times \frac{(-9)}{27 }  
  • Multiplication is a process of repetitive addition of integers.
  • Multiplication rules for integers :
  1. if two negative integers are multiplied then the product obtained is positive integer. i.e. $(-) \times(-)=+$
  2. If one negative and one positive integers are multiplied then the product obtained is negative integer. i.e. $(-) \times(+)=-$
  3. If both positive integers are multiplied then the product obtained is positive integer. i.e.$(+) \times(+)=+$
  • Therefore according to above rule we solve \frac{45}{(-5 ) }\times \frac{(-9)}{27 }  

       \frac{45}{(-5 ) }\times \frac{(-9)}{27 }  

       = -9 \times \frac{(-1)}{3}  \\= 3

Hence , value will be 3 .
