If the first chapter of a certain book is 40 pages long and makes up 20% of the book, how many pages does the entire book have?
Setler [38]

Answer:

200

Step-by-step explanation:

20% of a book = 40 pages

100% of a book = x pages

20/100 = 40/x                Cross multiply

20x = 100*40                 Combine the right

20x = 4000                    Divide by 20

20x/20 = 4000/20         Do the division

x = 200                           Answer

However, if you wish to complete problems like this in the future, pick one corner of the polygon and count how many places you mover right or left (x-axis. Right is going to be addition and left is going to be subtraction) and how many you move down or up (y-axis. up being addition and down being subtraction).
