Below is an instruction that describes a task. Write a response that appropriately completes the request in Spanish. Please answer in Spanish.

### Instruction:
 Matt did his homework for 150 minutes. He spent 30% of that time on math and 40% on science. He spent the remaining time on other subjects. How much time did Matt spend on homework in other subjects?


### Response:
 El tiempo total que Matt dedicó a hacer matemáticas y ciencias es el 30% + 40% = 70% del tiempo.
Esto significa que hizo la tarea de estas dos asignaturas durante 70/100 * 150 minutos = <<70/100*150=105>>105 minutos.
Matt dedicó 150 minutos - 105 minutos = <<150-105=45>>45 minutos a hacer la tarea de otras asignaturas.
