Question

what should be added to 1 by 4 1 by 5 and 1 by 6 to get 8​

Answer 1

Answer:

Let the number be x

(1/2+1/3+1/5)+x=4

l.c.m of 2,3,5=30

(15+10+6)/30=31/30

x=4–31/30

x=89/30

Answer 2

Let x be added

1/41 + x= 8

x= 8-1/41

= 328-1 (whole upon 41)

= 327/41

Therefore 327/41 should be added

2) 1/6 + x= 8

x=8-1/6

= 48-1 (whole upon 6)

= 47/6
