Question

The sum of two rational number is -3/5 if one them number is -9/20 find other

Answer 1

Answer:

One rational no. = - 9/20

Their sum = - 3/5

Let the other rational no. = a

-9/20 + a =-3/5

a = - 3/5 + 9/20

LCM =20

( -3/5 X 4/4 = - 12/20 )

a = - 12/20 + 9/20

a = - 3/20

Hence, the other rational no. is - 3/20 .
