When you read the word problem, you will observe that the word “each” stands for 1 unit . 

So if 1 bottle costs $10. then 25 bottles will cost the price of 1 bottle x 25. i.e. $10 x 25 = $250.

Answers:

1. 5 friends .  5 x (4/5) = 4 bags
2. 3x(2/7) = 6/7 of the carton of milk
3. 8x(3/4) = 6 bottles
4. 15 x (3/16) = 45/16 pizza

1 dozen cookies – 3/4 of  bag

10 dozen cookies –  x bags

x = 10 x 3/4 = 30/4 bags
