1st Proportional(a) = 2; 6
2nd Proportional(b) = 5; 8
3rd Proportional(c) = 6; 9
Formula Used:
4th Proportional(d) = (b x c)/a
Calculation:
According to the formula,
(5 x 6)/2 = 15
The fourth proportion is 15
Again,
(8 x 9)/6 = 12
The fourth proportion is 12
Ratio = 15 : 12
⇒ 5 : 4
∴ The ratio is 5 : 4
