A chemical consists of four compounds, A,B, C and D. 1 2 and D. 1/6 is A,2/5 is B,1/10 is C and the rest is D. What fraction of the chemical is D?​

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

⅔ + D = 1

D = 1 - ⅔

Lowest common multiple (LCM) = 3

D = ⅓

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
