The Healthy Wheat Bakery uses 560 pounds of flour to make 1,000 loaves of bread. Each loaf contains the same amount of flour. How many pounds of flour are used in each loaf of bread?
You can use place value patterns to help you find quotients. Dividing by 10, 100, or 1,000 is the same as multiplying by 0.1, 0.01, or 0.001.
- Underline the sentence that tells you what you are trying to find.
- Circle the numbers you need to use.
Use place-value patterns
Divide. 560 ÷ 1,000
Look for a pattern in these products and quotients.
So, __________ pound of flour is used in each loaf of bread.
Explanation:
So, 0.560 pound of flour is used in each loaf of bread.
Question 1.
As you divide by 10,100, and 1,000, how does the position of the decimal point change in the quotients?
Answer:
Move the decimal point to the left for as many places (steps) as there are zeros in the factor 10, 100, or 1000.
Explanation:
28 ÷ 10=2.8 — Move the decimal point one step to the left.
28÷ 100 = 0.28 –Move the decimal point two steps to the left. You need to write zeros in front of the number.
28 ÷ 1000 = 0.028 — Move the decimal point three steps to the left. You need to write zeros in front of the number.

Onions: 25.5 pounds ÷ _________
Think: 25.5 ÷ 1 =
25.5 ÷ 10 = ______
Green Peppers: 25.5 pounds ÷ _________
Think ________ ÷ 1 = _________
_________ ÷ 10 = _________
_________ ÷ 100 = _________
So, Liang used 25.5 pounds of tomatoes, _________ pounds of onions, and _________ pound of green peppers.
Answer:
Tomatoes: 25.5 pounds
Onions: 25.5 pounds ÷ 10
Think: 25.5 ÷ 1 =25.5
25.5 ÷ 10 =2.55
Green Peppers: 25.5 pounds ÷ 100
Think 25.5 ÷ 1 = 25.5
25.5 ÷ 10 =2.55
25.5÷ 100 = 0.255
So, Liang used 25.5 pounds of tomatoes, 2.55 pounds of onions, and 0.255 pound of green peppers.
