If there are 10 dear counted in a 1 km (to the second power) area of southern Lancaster county , what would be the estimated deer population in a 10 km(to the second power) area that includes this sample of land?

Question

"10 dear counted in a 1 km"

we have this ratio `10 deer : 1 km`

jim_thompson5910 · Answer

we can multiply both parts of the ratio by 10
why? because we want the `1 km` to turn into `10 km`

so we have

`10 deer : 1 km`
`10*10 deer : 10*1 km`
`100 deer : 10 km`

therefore we estimate 100 deer in 10 square km
