Answer 2

Calculating the Lifespan of a Skylark and a Swallow

To calculate the lifespan of a skylark, given that a swallow lives for 9 years, which is 3/8 of the skylark's lifespan, we can use the following steps:

1. Let's denote the skylark's lifespan as S and the swallow's lifespan as W. 2. We are given that the swallow's lifespan is 9 years, which is 3/8 of the skylark's lifespan. This can be represented as an equation: 9 = (3/8)S.

Solving for the Skylark's Lifespan

To find the skylark's lifespan, we can use the information provided and solve for S.

Using the given information, we have: 9 = (3/8)S

To solve for S: S = 9 / (3/8)

Let's calculate the value of S.

S = 9 / (3/8) S = 9 * (8/3) S = 24

So, the skylark's lifespan is 24 years.

Therefore, a skylark lives for 24 years.
