(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In each of the following the properties of a compound are given. In each case find A:B:C

1. 1/5 of A, 2/3 of B and the remainder of C.

2. 3/8 of A with B and C in the ratio 1:2.

3. A, B and C are mixed according to the ratios A:B= 2:5 and B:C=10:11.

2. Relevant equations

3. The attempt at a solution

I could only solve the 1st one:

The common denominator is 15 so 15/3*2=10 and 15/5*1=3. That means A and B are in the ratio 3:10.

15/15-13/15=2/15 so A:B:C are in the ratio of 10:3:2

Couldn't solve the other two. Please, help. Thanks.
