Answer:
3:9 is suppose.........
Verified answer
Answer:
A/c = A/b * B/c
=3/4 * 8/9
= 2/3
So a:c = 2:3
If you do not understand how it is done above i am providing another solution also.
a/b = 3/4,
so, 4a = 3b (by transposition)..........eq 1
b/c = 8/9,
So, 8c = 9b
also, b= 8c/9 ...... eq 2
Putting eq 2 into eq 1
4a = 3 ( 8c/9)
when you solve this, you will get
4a = 8c / 3
transpose 3 to the other side
4*3(a) = 8c
12a = 8c
so,
a/c = 8/12 = 2/3
Hence,
a:c = 2:3
Hope it helps.
