  2. The cruise ship traveled 529 kilometers in a 24-hour period. How many kilometers can the cruise travel in one week? The ship traveled 529 Km In a period of 24 hr or what it is the same in 1 day. 1 day ------ 529 Km 2 days -----1,058 Km 3 days -----1,587 Km 4 days -----2,116 Km 5 days ----- ? Km 6 days ----- ? Km 7 days -----? Km 1 week is 7 days If in 1 day traveled 529 Km In 7 days the ship will travel 7 days x 529 Km= The ship will travel 3703 Km in a week. 529 Km X 7 days 3703 Km

  3. Mrs. Eason has 21 students in each of her 6 math classes. What is the total number of math students that Mrs. Eason has in her classes? 21 Stud 21 Stud 21 Stud Mrs. Eason has 6 math classes Each math class has 21 students What the total number of students is 21 Stud 21 Stud 21 Stud Since each class has 21 students I could add each class number of students and get the total number. There is a faster method: multiplication. I can multiply the number of classes for the number of students 6 classes x 21 students = 126 students Answer: Mrs. Eason has 126 students in all her math classes.

  4. Mrs. Knight bought 854 bottles of water for field Day at Willbern Elementary. Each bottle contained 16 ounces of water. How many ounces of water did Mrs. Knight buy altogether? Bought 854 bottles 1 bottle 16 ounces Total number of ounces in all the bottles 16 ounces X 5 80 ounces 16 ounces 854 bottles times 16 = ??? ounces So if 1 bottle has 16 ounces, 2 bottles have the double, three bottles have the triple, etc., etc. As I put in the drawing in section 2 If 1 bottle = 16 ounces 854 bottles = 854 x 16 ounces 854 . X 16 oz 5124 . + 8540 . 13,664 oz Answer: Mrs. Knight bought 854 bottles with a total of 13, 664 ounces of water.

  5. An 8-ounce package contains 24 cookies. If there are 48 packages to a case, how many cookies are there in each case? 1package of 8 oz has 24 cookies 48 packages is 1 case Total number of cookies in 1 case = ??? 24 cookies 1 case =48 packages If 1 package has 24 cookies 1 case has 48 packages I need to multiply the number of packages in a case for the number of cookies in each package 48 packages x 24 cookies= Answer: There are 1,152 cookies in each case 48 X 24 192 + 960 1,152

  6. Patricia and 2 friends went shopping for birthday presents. They bought presents costing $125, $18, $95, and $46. What is the best estimate of the total cost of the gifts? Estimating 125 --- 130 18 ----- 20 95 ----- 100 46 ----- 50 They bought presents The cost was $125, $18, $95, and $46 Estimate the total cost Estimate is make an approximate calculation of the cost Answer: Patricia and friends spend around $300 buying their presents I need to add the estimation for each present 130 + 20 100 50 300

  7. The distance from San Antonio to Houston is 228 miles. The distance from Houston to New Orleans is 376 miles. Alexandria is 320 miles from New Orleans. Which is the best estimate of the total miles from San Antonio to Alexandria? San Antonio to Houston 228 miles Houston to New Orleans 376 miles New Orleans to Alexandria 320 miles San Antonio to Alexandria ??? miles 228 miles 228 ---- 200 miles 376 miles 376 ---- 400 miles 320 miles 320 ---- 300 miles ??? miles I estimate the miles to the hundreds place and then add all the distances 200 + 400 300 900 Answer: There are approximate 900 miles from San Antonio to Alexandria

  8. Janice wants to buy a pair of hightop Reeboks for $42.95 , 2 pairs of blue jeans for $34.50 each and a sweatshirt on sale for $19.99. Which of the following is a reasonable total before tax is added? Janice buy Reebok at $42.95 2jeans at $34.50 each one A sweatshirt at $19.99 What is the best estimation 42.95 ----- 40 34.50 ---35 Then 35 + 35 = 70 199.99 --- 20 The first thing to do is to estimate each individual cost. Second is to multiply the cost for jeans since she bought 2 pairs. Last I need to add all the estimations Answer: The answer is any choice that has 130 included. The option cannot be less than 130 or higher than 130 by itself. It should be a range that include 130 35 x 2 = 70 40 +70 + 20 = 130 Now I look in the answers which one matches this information

  9. The teacher passes out 7 supply totes in the classroom. Each tote contained 15 markers, 4 pairs of scissors, and 4 rules. How many total of markers did she pass out? Passes 7 totes Each tote has 15 markers 4 pairs of scissors 4 rulers How many markers (only) = ??? 15 markers 15 markers 15 markers 15 markers 15 markers 15 markers 15 markers If each tote has 15 markers I just need to multiply the number of totes for the number of markers in each tote The same is to multiply the number of markers for the number of totes 15 X 7 105 Answer: The teacher pass out 105 markers

  10. The movie theater ordered 14 cases of popcorn at $5.50 per case. Each case has 22 bags of popcorn.

I do not need the cost 22 bags in each case 22 bags times 14 cases Answer: The theater received 308 bags of popcorn Since each case has 22 bags of popcorn and I have 14 cases I just need to multiply the number of cases for the number of popcorn bags in each 14 x 22 28 280 308

  11. Which statement could be used to find the number of kilometers the ship could travel in one week if they traveled the same distance every day? 1 day = ???? km I need to choose the best option from a group of answer to decide the number of Km traveled in 1 week considering that it is traveled the same each day I know that I can multiply the number of km traveled each day for the number of days in a week 2 day = ???? km 3 day = ???? km 4 day = ???? km 5 day = ???? km 6 day = ???? km 7 day = ???? km I need to know the number of hours in 1 week This is what I thought I should do initially I need to add the number for each day so this will give me a smaller number I need to add the number for each day so this will give me a smaller number Multiply the number of kilometers by the hours in one day. Multiply the number of kilometers by the number of days in one week. Divide the numbers of kilometers by the number of hours in a day. Divide the number of kilometers by the number of days in one week. Answer: Answer b) will be the best option to calculate the number of kilometers traveled by a ship in one week.
