Answer 1

☞Question.

what should be added to 1/7to get 1 ?

☞Solution.

let added number be $\sf\red{ x}$

then, $\sf\green{ 1/7 + x = 1}$

➝ $\sf\green{ x = 1/1 - 1/7}$

$\sf\red{l.c.m \:is\: 7 }$

➝ $\sf\green{ x = 7 - 1 / 7}$

➝ $\sf\green{ x = 6 / 7}$

☞So, $\sf\green{ 6 / 7}$ be added to $\sf\red{ 1/7 }$ for get one.
