Solutions

Question 1
To find the number of pots of seeds, divide the total number of seeds by the number of seeds in each pot: 7,880 ÷ 25 = 315. Therefore, Mr. Martin planted 315 pots of seeds.

Question 2
The number of shirts left can be found by subtracting the number of shirts sold from the number of shirts ordered. Therefore, the number of shirts left is 3000 - 2200 = 800. Since the answer is already rounded to the nearest thousand, no further rounding is necessary.

Question 3
To find the speed of the marathon runner in miles per hour, first convert the time to hours. 3 hours and 45 minutes is equivalent to 3.75 hours. Then, divide the total distance (26.2 miles) by the time in hours (3.75 hours): 26.2/3.75 = 6.98667. Since we need to round to the nearest thousand if the answer is greater than 1000, we round up to 7.

Question 4
To find the total number of apples, we simply have to multiply the number of boxes by the number of apples in each box. So, 24 boxes x 430 apples/box = 10320 apples. Since we need to round to the nearest thousand, we look at the last three digits of the answer. The last three digits are '320', which is less than half of '1000', so we round down and get 10000 apples.

Question 5
To find out the number of stuffed animals produced in a week, we need to multiply the daily production by 7 (as there are 7 days in a week). So, 7,350 x 7 = 51,450. Since we need to round the answer to the nearest thousand, we get 51,000.

Question 6
To find out how many toys each machine can make approximately, we can divide the total number of toys produced by the number of machines used. Therefore, the calculation is: 1,250 ÷ 5 = 250. So each machine can make approximately 250 toys.

Question 7
To find the total number of pages, we simply have to multiply the number of books by the number of pages in each book. So, 15 books x 780 pages/book = 11700 pages. Since we need to round to the nearest thousand, we look at the last three digits of the answer. The last three digits are '700', which is less than half of '1000', so we round down and get 12000 pages.

Question 8
To find the number of cupcakes left, we need to subtract the number of cupcakes sold from the number of cupcakes made. That is: 2,543 - 1,369 = 1,174. Therefore, the answer is 1,174.

Question 9
To find out the number of gallons of milk sold in a month, we need to multiply the weekly sales by 4 (as there are approximately 4 weeks in a month). So, 3,420 x 4 = 13,680. Since we need to round the answer to the nearest thousand, we get 14,000.

Question 10
To find the approximate number of children, subtract the number of adults from the total number of people. 1256 - 436 = 820. Therefore, about 820 people were children.
