In one day Sasha got 1 hour of sleep for every 3 hours she was awake if there are 24 hours in a day how many hours of sleep did

Gre4nikov [31]

Answer:

Hours slept = 6 hours

Hours awake = 18 hours

Step-by-step explanation:

Sasha got 1 hour of sleep for every 3 hours she was awake.

So,

This means:

Slept : Awake = 1 : 3

Total hours in a day = 24 hours

Let

Hours slept = 1x and hours awake = 3x

Hence,

1x + 3x = 24 hours

4x = 24

Divide both sides by 4

x = 24 / 4

x = 6

So,

Hours slept = 1(6) = 6 hours

Hours awake = 3(6) = 18 hours

$\rule[225]{225}{2}$

Hope this helped!
