Ireland Hernandez · Answer 1

Infants need 16 hrs ... children of age 3 - 6 require 25% less ...

16 - 0.25 (16) = 16 - 4 = 12 hrs <=

Mark Roberson · Answer 2

16 * 0.25 = 4

16 - 4 = 12

So therefore, 3-6 year old aneed 12 hours of sleep.

Or you could solve it this way:

100 - 0.25 = 0.75

16 * 0.75 = 12

Either of the two ways you would get 12
