Answer 1

Answer:

If Amy requires 3 different substances A,B,C in the ratio 5:3:4 and 30 grams of substance A was administered, then number of grams of B and C are 18 and 24 respectively.

Step-by-step explanation:

Given the ratio of substances A:B:C is 5:3:4

then amount of A can be taken as 5x

amount of B as 3x and amount of C as 4x

Given amount of substance A is 30 grams.

That is $5x=30$

$x=\frac{30}{5} \\ = 6$

Therefore amount of substance B is $3x = 3*6\\ = 18$grams

Amount of substance C is $4x=4*6 \\ = 24$grams

So the number of grams of B and C are 18 grams and 24 grams respectively
