Answer:
answer is 89/30
Step-by-step explanation:
considering that x=(1/2+1/3+1/5)
now suppose Y is the number that should be added to x to get 4=
X+Y=4
Y=4-X
Now calculate the value of X
LCM of 2,3 and5
is =2x3x5=30
X= ((LCM/2)+(LCM/3)+(LCM/5))/LCM
X=( 15+10+6)/30
X=31/30
therefore The number Y is
Y=4–(31/30), LCM of 30 and 1 is 30.
Y=((LCM*4)-(LCM*31/30))/30
Y=(120–31)/30
Y=89/30 Ans.
