QUESTION

What should be added to (1/2+1/3+1/5) to get 4?

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.

Answer 2

Answer:

-37/12

Step-by-step explanation:

let the req. no. be x

1/2 + 1/3 + 1/4 + x = -2

6+4+3/12 + x = -2

x = -2 - 13/12

x = -24 -13/12

x = -37/12
