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

### Instruction:
 一根40米长的绳子按照2:3的比例被切成两段。较短的那段有多长？


### Response:
 绳子被切成了2 + 3 = <<2+3=5>>5段。
所以每段长度为40/5 = <<40/5=8>>8米。
由于较短的那段由2段组成，所以它的长度为8 x 2 = 16米。
