I will help you with this
you have to post your method of solving for the rest questions by following this method.
don't think we will just post our answers

let name the number as x
x + (1/7)x = 56
taking LCM as 7
(7x+x)/7 = 56
8x=56*7
x= 49

the second condition is
x - (1/7)x = y
taking lcm as 7
(7x -x) /7 = y
6x / 7 =y
y= 6x / 7
y=(6*47)/7
42

now try to solve the rest like this as you have the idea now
