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

### Instruction:
Misty's favorite number is 3 times smaller than Glory's favorite number. If Glory's favorite number is 450, what's the sum of their favorite numbers?

### Response:
Misty's favorite number is 3 times smaller than Glory's, meaning her favorite number is 450 / 3 = <<450/3=150>>150
Adding their favorite numbers gives a sum of 150 + 450 = <<150+450=600>>600
#### 600
