fish 12%
snake 7%
hamster 11%
cat 21%
dog 23%
bird 26%

Explanation:

Step1: Convertir el porcentaje a decimal

Multiplicar el porcentaje de personas que eligieron pájaro (26%) por 0.01 para convertirlo a decimal.
$$26\%=26\times0.01 = 0.26$$

Step2: Calcular el número de personas

Multiplicar el decimal (0.26) por el número total de ciudadanos encuestados (130000).
$$0.26\times130000 = 33800$$

Answer:

33800
