Let x represent the first part of 94. Then 94 - x is the second part. The fifth part of the first part is: , and the eighth part of the second part is: .

These two numbers are in the ratio 3:4, so:

Cross-multiply:

Cross-multiply:

Check: The fifth part of 30 is 6, and the eighth part of 64 is 8 and 6 is to 8 as 3 is to 4.

********************************************

Half of A's part is equal to one-third of B's part:

Half of A's part is equal to one-sixth of C's part:

Then:

Check:

Half of 360 is 180, one-third of 540 is 180, and one-sixth of 1080 is 360. 360 + 540 + 1080 = 1980.

Let f=first part and s=the second
f+s=94
f=94-s
.
.2f/.125s=3/4
.2(94-s)/.125s=3/4
(18.8-.2s)/.125s=3/4
4(18.8-.2s)=3*.125s
75.2-.8s=.375s
1.175s=75.2
s=64
f=30
I'll try to get back to you regarding the 2nd part.
