   Step 1: Identify the total number of bulbs: 1,365 Step 2: Identify the number of flower beds: 7 Step 3: Divide the total bulbs by the number of beds: 1,365 ÷ 7 Step 4: Calculate the division: 7 × 195 = 1,365 Step 5: Therefore, 1,365 ÷ 7 = 195 Each flower bed should receive 195 bulbs.

3. A farmer plants corn in a rectangular field that is divided into 15 equal rows. Each row contains 28 corn plants arranged in a straight line. If you look at the field from above, how many corn plants are there in total? Answer: 420 Solution: The field has 15 rows of corn plants. Each row contains 28 corn plants. To find the total number of plants, multiply the number of rows by the number of plants in each row: 15 × 28.
   Full step-by-step solution

   Step 1: The field has 15 rows of corn plants. Step 2: Each row contains 28 corn plants. Step 3: To find the total number of plants, multiply the number of rows by the number of plants in each row: 15 × 28. Step 4: First, multiply 15 by 20: 15 × 20 = 300. Step 5: Then, multiply 15 by 8: 15 × 8 = 120. Step 6: Add the two results: 300 + 120 = 420. The total number of corn plants is 420.

4. 2,592 ÷ 12 = ? Answer: 216 Solution: Set up the division: 2,592 ÷ 12 Divide 25 (from 2,592) by 12. 12 × 2 = 24, so write 2 above the 5. Subtract: 25 - 24 = 1.
   Full step-by-step solution

   Step 1: Set up the division: 2,592 ÷ 12 Step 2: Divide 25 (from 2,592) by 12. 12 × 2 = 24, so write 2 above the 5. Subtract: 25 - 24 = 1. Step 3: Bring down the next digit, which is 9, making 19. Step 4: Divide 19 by 12. 12 × 1 = 12, so write 1 above the 9. Subtract: 19 - 12 = 7. Step 5: Bring down the last digit, which is 2, making 72. Step 6: Divide 72 by 12. 12 × 6 = 72, so write 6 above the 2. Subtract: 72 - 72 = 0. Step 7: The final answer is 216.

5. A community garden is planting flowers in their new flower beds. They have 1,536 flower bulbs that need to be divided equally among 12 identical flower beds. How many bulbs should be planted in each bed? Answer: 128 Solution: Identify the total number of bulbs: 1,536 Identify the number of flower beds: 12 Divide the total bulbs by the number of beds: 1,536 ÷ 12 Calculate the division: 12 × 128 = 1,536 Therefore, 1,536 ÷ 12 = 128 The answer is 128 bulbs per flower bed.
   Full step-by-step solution

   Step 1: Identify the total number of bulbs: 1,536 Step 2: Identify the number of flower beds: 12 Step 3: Divide the total bulbs by the number of beds: 1,536 ÷ 12 Step 4: Calculate the division: 12 × 128 = 1,536 Step 5: Therefore, 1,536 ÷ 12 = 128 The answer is 128 bulbs per flower bed.

6. A farmer plants corn in a rectangular field that is divided into 15 rows and 20 columns of equal square plots. If you look at the field from above, you can see the grid pattern of all the plots. What is the total number of corn plots in the field? Answer: 300 Solution: The field has 15 rows of plots The field has 20 columns of plots To find the total number of plots, multiply the number of rows by the number of columns 15 × 20 = 300 The total number of corn plots is 300
   Full step-by-step solution

   Step 1: The field has 15 rows of plots Step 2: The field has 20 columns of plots Step 3: To find the total number of plots, multiply the number of rows by the number of columns Step 4: 15 × 20 = 300 Step 5: The total number of corn plots is 300

7. Leo is organizing 2006 photographs into an album. Each page can hold 17 photographs. If Leo fills every page completely, how many pages will be filled? Answer: 118 Solution: Divide the total number of photographs (2006) by the number that fit on one page (17). 2006 ÷ 17 = 118. Leo will fill 118 pages completely.
   Full step-by-step solution

   Step 1: Divide the total number of photographs (2006) by the number that fit on one page (17). Step 2: 2006 ÷ 17 = 118. Leo will fill 118 pages completely.

8. A farmer plants corn in a rectangular field that is divided into 12 equal rows and 15 equal columns of square plots. If each square plot has an area of 16 square meters, what is the total area of the entire corn field in square meters? Answer: 2880 Solution: Find the total number of square plots in the field. The field has 12 rows and 15 columns, so total plots = 12 × 15 = 180 plots. Find the total area of the field.
   Full step-by-step solution

   Step 1: Find the total number of square plots in the field. The field has 12 rows and 15 columns, so total plots = 12 × 15 = 180 plots. Step 2: Find the total area of the field. Each plot has an area of 16 square meters. Total area = (number of plots) × (area per plot) = 180 × 16. Step 3: Calculate 180 × 16. First, 100 × 16 = 1600 Then, 80 × 16 = 1280 Now add: 1600 + 1280 = 2880 Step 4: State the final answer. The total area of the corn field is 2880 square meters.

9. A rectangular classroom floor is tiled with square tiles. There are 28 tiles along the length of the room and 36 tiles along the width. If you look at the floor from above, how many total tiles cover the entire floor? Answer: 1008 Solution: The problem describes a rectangular floor with tiles arranged in rows and columns. There are 28 tiles along the length (this is like the number of columns).
   Full step-by-step solution

   Step 1: The problem describes a rectangular floor with tiles arranged in rows and columns. Step 2: There are 28 tiles along the length (this is like the number of columns). Step 3: There are 36 tiles along the width (this is like the number of rows). Step 4: To find the total number of tiles, multiply the number of tiles in one row by the number of rows: 28 × 36. Step 5: Calculate 28 × 36: First, 20 × 36 = 720, then 8 × 36 = 288. Step 6: Add the partial products: 720 + 288 = 1008. The total number of tiles is 1008.
