Answer:
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
[tex] \frac {5 + 12 + 3}{30} + D = 1 [/tex]
[tex] \frac {20}{30} + D = 1 [/tex]
⅔ + D = 1
D = 1 - ⅔
Lowest common multiple (LCM) = 3
[tex] D = \frac {3 - 2}{3} [/tex]
[tex] D = \frac {1}{3} [/tex]
D = ⅓
