You can put this solution on YOUR website! We can substitute a number, do the math, then find the ratios.
Say Amanda has 12 books. 3/4 of that, 9 is 1/6 of Balas's so Bala has 54, and Calvin has 27.
B:C:A is 54:27:9 which are all multiples of 9 so we reduce to 6:3:1 as the ratio.

Then Bala has: 6A, and Calvin has: 3A
Ratio of Bala’s to Calvin’s to Amanda’s: 6A:3A:A, or
