5/7- x = 1/21
therefore x = 1/21 +5/7
= (7+105)/147
= 112/147
therefore x = 1/21 +5/7
= (7+105)/147
= 112/147

first no is 5/7
let second no is x
5/7-x= 1/21
x= 1/21- 5/7
lcm is 21
1/21*1
5/7*3
1/21
15/21
x= 1/21-15/21
x= 1-15/21
x= 14/21
x = 2/3
let second no is x
5/7-x= 1/21
x= 1/21- 5/7
lcm is 21
1/21*1
5/7*3
1/21
15/21
x= 1/21-15/21
x= 1-15/21
x= 14/21
x = 2/3
