D = ⅓

Step-by-step explanation:

Given the following data;

A = ⅙

B = ⅖

C = ⅒

To find what fraction of the chemical is D;

The sum of all the fractions of the chemical compound must be equal to one (1).

A + B + C + D = 1

Substituting the values, we would have;

⅙ + ⅖ + ⅒ + D = 1

Lowest common multiple (LCM) = 30

$\frac {5 + 12 + 3}{30} + D = 1$

$\frac {20}{30} + D = 1$

⅔ + D = 1

D = 1 - ⅔

Lowest common multiple (LCM) = 3

$D = \frac {3 - 2}{3}$

$D = \frac {1}{3}$

D = ⅓
