Here are the step-by-step solutions for the problems on the worksheet.
1) Aiden found 6 pieces of milk chocolate in two boxes of assorted chocolate. How many pieces of milk chocolate would he probably find in 12 boxes of assorted chocolate?
*
Step 1: Find out how many pieces of milk chocolate are in just
one box.
* 6 pieces $\div$ 2 boxes = 3 pieces per box.
*
Step 2: Multiply that amount by the new number of boxes (12).
* 3 pieces $\times$ 12 boxes = 36 pieces.
2) A bookstore sold 16 books in 5 days. At this rate of sales, how many days will it take the store to sell 96 books?
*
Step 1: Figure out how many times bigger the new goal (96 books) is compared to the original amount (16 books).
* 96 $\div$ 16 = 6.
* This means they need to sell 6 times as many books.
*
Step 2: Since they are selling 6 times as many books, it will take 6 times as long.
* 5 days $\times$ 6 = 30 days.
3) Steve washed 15 cars in 3 hours. How many cars can he wash in 7 hours?
*
Step 1: Find Steve's speed per hour (unit rate).
* 15 cars $\div$ 3 hours = 5 cars per hour.
*
Step 2: Multiply his hourly speed by the new time (7 hours).
* 5 cars/hour $\times$ 7 hours = 35 cars.
4) A photographer can take 12 pictures in 5 minutes. How long will it take him to take 132 pictures?
*
Step 1: Find out how many "sets" of 12 pictures are in 132 pictures.
* 132 $\div$ 12 = 11 sets.
*
Step 2: Since each set takes 5 minutes, multiply the number of sets by 5.
* 11 sets $\times$ 5 minutes = 55 minutes.
5) 12 rotten tomatoes are usually found in every four boxes. How many rotten tomatoes would likely be found in 14 boxes?
*
Step 1: Find out how many rotten tomatoes are in
one box.
* 12 rotten tomatoes $\div$ 4 boxes = 3 rotten tomatoes per box.
*
Step 2: Multiply that rate by the new number of boxes (14).
* 3 rotten tomatoes $\times$ 14 boxes = 42 rotten tomatoes.
6) A pack of six cans of coffee cost $12. How much would 18 cans of coffee cost?
*
Step 1: Compare the number of cans. You want 18 cans, and the price is given for 6 cans.
* 18 $\div$ 6 = 3.
* You are buying 3 times as many cans.
*
Step 2: Multiply the original price by 3.
* $12 $\times$ 3 = $36.
Final Answer:
1) 36 pieces
2) 30 days
3) 35 cars
4) 55 minutes
5) 42 rotten tomatoes
6) $36
