A = 3/2B.
=> A/B = 3/2 Divide symbol can be considered as Ratio, So,
=> A:B = 3:2.

When it comes to the ratio 3:2.
The ratio value can be added to get the whole amount.
Here, the whole amount can be represented as 5 parts(Adding 2+3 = 5).

And according to the ratio (A:B = 3:2), B equals to 2/5 part of the whole amount(1210), which can be represented as;
2/5(1210) = 484.

4x/15 = 2y/5.
x/y = 3/2.
3+2 = 1210.
5 = 1210.
1 = 242.
y = 2y.
2 * 242.
= 484

Why should we have to find a : b?

Here we can directly multiply the 2/5*1210. Right?
