Question

are the rational nos. -9/12 and 8/-2 equal​

Answer 1

ANSWER

SO, FIRST WE WILL BRINGTHE MINUS SIGN FROM THE DENOMINATOR TO THE NUMERATORS

8/-2        WE WILL MULTIPLY BOTH THE NUMERATOR AND DENOMINATOR BY -1   SO IT WILL BECOME -8/2

THEN WE WILL FIND THE LCM OF THE DENOMINATOR i.e. 12

SO -9/12  WILL REMAIN AS IT IS

THEN WE HAVE MAKE DENOMINATOR OF THE  -8/2  TO 12

SO WE WILL MULTIPLY BOTH NUMERATOR AND DENOMINATOR BY 6

THEN IT WILL BECOME -48/12

BOTH THE NO. HAS SAME DENOMINATOR

IN RATIONAL NO.  NEGATIVE NO. WHOSE VALUE IS LESS IS CONSIDERED TO BE LARGEST

SO -9/12   >   -48/12

HOPE THIS WILL HELP YOU CHILD
