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.
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.
