Question

the sum of two rational number is 4 /9 if one of them is 13 / 6 then find the other​

Answer 1

let other number be x

one number = 13/6

sum of number = 4/9

13/6 +x = 4/9

transpose the values

13/6 - 4/9 = x

lcm = 6*9 =54

13.*9 / 6*9 - 4*6 / 9*6 = x

117 /54 - 24/54 = x

93 / 54 = x

they are divisible so 93/54 = - 31/18

so number = - 31/18
