Blood is a specialized fluid tissue that is being circulated around the body for many purposes. Given that 15 percent of the total blood is in located at the brain; we can just get the amount of blood in the brain at rest by multiplying the total volume of blood (5.2L) with the decimal equivalent of 15% which is 0.15.

`= 5.2 Liters of blood * ((15%)/(100%)) `

`= 5.2 Liters of blood * (0.15) `

`= 0.78 ` Liters of blood is present in the brain at rest.
