Answer:

15 students

Step-by-step explanation:

Let x = number of students in the class

students * fraction of boys = boys

x * 4/5 = 12

Multiply each side by 5/4

x * 4/5 (5/4) = 12*5/4

x =15

There are 15 students

Answer:

15 students

Step-by-step explanation:

Step 1: Divide 12 by 4 because if 12 is 4/5, then to find 1/5 you have to divide 4/5 by 4 and 12 by 4

12/4=3

Step 2: Add 12+3 because 4/5+1/5=5/5

12+3=15

There are 15 students in the class, hope this helps!

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,

<u>This means:</u>

Slept : Awake = 1 : 3

Total hours in a day = 24 hours

<u>Let </u>

Hours slept = 1x and hours awake = 3x

<u>Hence,</u>

1x + 3x = 24 hours

4x = 24

Divide both sides by 4

x = 24 / 4

x = 6

<u>So,</u>

Hours slept = 1(6) = 6 hours

Hours awake = 3(6) = 18 hours

\rule[225]{225}{2}

Hope this helped!
