Question :-
What should be added to [ 1/2 + 1/3 + 1/5] to get 4?
Answer :-
89/30
Solution :-
Let the number be x
According to the question :-
[ 1/2 + 1/3 + 1/5] + x = 4
Transpose [ 1/2 + 1/3 + 1/5] to RHS
⇒ x = 4 - [ 1/2 + 1/3 + 1/5]
Remove brackets
⇒ x = 4 - 1/2 - 1/3 - 1/5
Taking LCM
⇒ x = 4(30)/1(30) - 1(15)/2(15) - 1(10)/3(10) - 1(6)/5(6)
⇒ x = 120/30 - 15/30 - 10/30 - 6/30
⇒ x = 120/30 - 31/30
⇒ x = (120 - 31)/30
⇒ x = 89/30
Verification :-
[ 1/2 + 1/3 + 1/5] + x = 4
Substituting value of x
⇒ [ 1/2 + 1/3 + 1/5] + 89/30 = 4
⇒ 1/2 + 1/3 + 1/5 + 89/3 = 4
Taking LCM
⇒ 1(15)/2(15) + 1(10)/3(10) + 1(6)/5(6) + 89/30 = 4
⇒ 15/30 + 10/30 + 6/30 + 89/30 = 4
⇒ (15 + 10 + 6 + 89)/30 = 4
⇒ 120/30 = 4
⇒ 4 = 4
