Question

the sum of two rational numbers is 8/7.if one of the no.s is 1/14 find the other ​

Answer 1

Let the other number be x

1/14+ x= 8/7

x= 8/7-1/14

(LCM of 7 and 14= 14)

x= (8×2/7×2)-(1×1/14×1)

x= 16/14-1/14

x= 15/14

OTHER NUMBER IS 15/14

Answer 2

let the other rational number be x

1/14+ x= 8/7  

x= 8/7-1/14

(LCM of 7 and 14= 14)

x= (8×2/7×2)-(1×1/14×1)

x= 16/14-1/14

x= 15/14
