3. Emma is organizing her sticker collection into an album. Each page of the album holds 8 stickers. If Emma has 72 stickers in total, how many pages will she fill completely? Answer: 9 Solution: We are told that each page holds 8 stickers and Emma has 72 stickers in total. We want to find how many pages will be filled completely. Identify the operation needed.
   Full step-by-step solution

   We are told that each page holds 8 stickers and Emma has 72 stickers in total. We want to find how many pages will be filled completely. Step 1: Identify the operation needed. Since each page holds 8 stickers, the number of pages filled completely is found by dividing the total number of stickers by the stickers per page. Step 2: Write the division. Total stickers = 72 Stickers per page = 8 So, number of pages = 72 ÷ 8. Step 3: Perform the division. 72 ÷ 8 = 9. Step 4: Interpret the result. Since 72 divided by 8 equals exactly 9, Emma will fill 9 pages completely with no stickers left over. Final answer: 9 pages.

4. A school is planning a field trip and needs to transport 96 students. Each school bus can carry 24 students. How many buses are needed to transport all the students?

   Full step-by-step solution

   Step 1: Identify the total number of students: 96 Step 2: Identify how many students each bus can carry: 24 Step 3: Divide the total students by the capacity of one bus: 96 ÷ 24 Step 4: Calculate the division: 24 × 4 = 96, so 96 ÷ 24 = 4 Step 5: Since we need whole buses to carry all students, we need 4 buses. The answer is 4.

5. Liam is organizing his sticker collection into albums. He has 72 stickers and wants to put 8 stickers on each page. How many pages will Liam need for all his stickers? Answer: 9 Solution: We are told that Liam has 72 stickers and wants to put 8 stickers on each page. To find the number of pages needed, we divide the total number of stickers by the number of stickers per page.
   Full step-by-step solution

   We are told that Liam has 72 stickers and wants to put 8 stickers on each page. To find the number of pages needed, we divide the total number of stickers by the number of stickers per page. Step 1: Write the division expression. Total stickers = 72 Stickers per page = 8 Number of pages = 72 ÷ 8 Step 2: Perform the division. We can think: how many times does 8 go into 72? 8 × 9 = 72 Step 3: Interpret the result. Since 72 ÷ 8 = 9, Liam will need 9 pages to fit all the stickers. Step 4: Check the reasoning. If each page holds 8 stickers, then 9 pages hold 9 × 8 = 72 stickers, which matches the total. So the answer is correct. Final answer: 9
