Question

What should be added in (1/2+1/3-1/5)to get 4 (write in notebook and send)​

Answer 1

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

i.e.

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.
