First find the LCM of a, b, c.
The inverse ratio of a : b : c is 1/a : 1/b : 1/c
Multiply the LCM of a,b,c to each term of
inverse, you will get the exact value of ratio.
LCM of a, b, c = abc
So the inverse ratio is 1/a xabc: 1/b x abc : 1/c x abc = bc : ac : ab
Similarly, do withthem
upto 4 to five positions.
Example:
As the ratio of 1 : 2 : 3
inverse of the ratio is given by
Reciprocal ratio = 1/1 :1/2 : 1/3
LCM of 1, 2, 3 is 6 so we multiply the reciprocal of each term by 6
1/1 x 6 : 1/2 x6 : 1/3 x6 = 6 : 3 : 2
