Eng-> Between A and B they have $128. If three-fifths of part A is equivalent to a ninth of part B. How much does B have?  Regards

Esp-> Entre A y B tienen $128. Si tres quintas partes de la parte A es equivalente a un noveno de la parte B. ¿Cuánto tiene B? Saludos cordiales.

[MAF]Agus:
A + B = 128 (1)

3/5 A = 1/9 B
A = 5/27 B (2)

5/27 B + B = 128
32/27 B = 128
B = 128*27/32
B = 108
