**Concepts and Skills**

Question 1.

Explain how to find 14 Ã— 19 by breaking apart the factors into tens and ones and finding the sum of the four partial products.

Answer: 266.

Explanation:

We can break 14 and 19 as 10+4 and 10+9 and to get the answer we will multiply both of the first two numbers by the other two. So we will multiply 10(10+9) and 4(10+9), then the values will be (100+90) and (40+36). By adding both we will get 100+90+40+36= 266

Question 2.

Explain how to find 40 Ã— 80 using mental math.

Answer: 3600.

Explanation:

By using mental math we will multiply 4Ã—8= 36 and then we will add zeros, so the answer will be 3600.

**Estimate the product. Choose a method.**

Question 4.

19 Ã— $67

$ ____

Answer: $1,273.

Explanation:

By breaking apart the factors into tens and ones and we can find the sum of the four partial products.

19Ã—67= (10+9)Ã—(60+7)

= (10Ã—60)+(10Ã—7)+(9Ã—60)+(9Ã—7)

= 600+70+540+63

= $1,273.

Question 5.

43 Ã— 25

Answer: 1,075.

Explanation:

By breaking apart the factors into tens and ones and we can find the sum of the four partial products.

43 Ã— 25= (40+3)Ã—(20+5)

= (40Ã—20)+(40Ã—5)+(3Ã—20)+(3Ã—5)

= 800+200+60+15

= 1,075.

Question 6.

54 Ã— 83

Answer: 4,482.

Explanation:

By breaking apart the factors into tens and ones and we can find the sum of the four partial products.

54 Ã— 83= (50+4)Ã—(80+3)

= (50Ã—80)+(50Ã—3)+(4Ã—80)+(4Ã—3)

= 4000+150+320+12

= 4,482.

**Estimate. Then find the product.**

Question 25.

A city is having a festival in a local park. Alisonâ€™s Bakery has agreed to donate $1,200 worth of baked goods for the event. The city wants to order 12 loaves of holiday bread, 18 dozen biscuits, 12 dozen bagels, and 14 dozen multigrain rolls.

A. Is the cost of the baked goods under the $1,200 donation limit? Use pictures, numbers, or words to explain how you found your answer.

Answer: Yes, the donation is under $1,200.

Explanation:

As the city ordered 12 loaves of holiday bread, 18 dozen biscuits, 12 dozen bagels, and 14 dozen multigrain rolls. And holiday bread costs $20, one dozen busicuits costs $12, and one dozen bagels costs $28, 1 dozen multigrain rolls costs $22. So by adding them

(12Ã—20)+(12Ã—18)+(12Ã—28)+(14Ã—22) we will get $1,100 which is less than $1,200

Question 25.

B. If yes, what could the city add to the order? If no, what could the city remove from the order?

Answer: The city can add whatever they want with remaining $100. As $1,200-$1,100= $100.
