Blue balls : Total number.
Total number of balls = 50 + 45 + 65 = 160
Blue balls : Total number.
= 65: 160 Divide both by 5.
= 13 : 32
= 13/32. That is the ratio.
Because a square has 4 sides, you would multiply the 8 meters by 4. That would mean that the entire room is 32 squared meters. Then multiply the 32 meters by the cost ($35.00). The total cost of the new carpet is $1,120

We know that there are 24 hours in one day. We are going to use this for the whole question. For each question we are going to do 24 hours multiplied by the decimal form of the percentage for that particular activity (we find the decimal value by moving the decimal twice to the left)
School: 24*.25 = 6 hours
Eating: 24*.1 = 2.4 hours
Sleep: 24*.4 = 9.6 hours
Homework: 24*.1 = 2.4 hours
Free time: 24*.15 = 3.6 hours
Hope this helps!
