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

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?
