Answer:-  The value of 4 in (a) is tenth position when we dividing it by 100 it changes its quotient and becomes less value because
when the number is in right of the decimal it has less value. Likewise, when the value is dividing it with 1000 its value becomes 0. something. When we divide any number with any number its gradually decreases and distribute its value to the dividing number.

Question 3.
A manufacturer made 7,234 boxes of coffee stirrers. Each box contains 1,000 stirrers. How many stirrers did they make? Explain your thinking, and include a statement of the solution.

Answer:- There are totally 7234 boxes and in each box they contains 1000 stirrers. That means we have to multiply 7234 boxes with
1000 then we get the answer. In the same way, I have elaborated my answer.

The No. of boxes of coffee stirrers made by Manufacturer = 7234
Each box contains coffee stirrers  = 1000
Total Number of coffee stirrers = No. of boxes X Each box contains coffee stirrers
=  7234 X 1000
= 7,23,4000
Therefore, The total No. of coffee stirrers are 7,23,4000.

Question 4.
A student used his place value chart to show a number. After the teacher instructed him to multiply his number by 10, the chart showed 3,200.4. Draw a picture of what the place value chart looked like at first.

Explain how you decided what to draw on your place value chart. Be sure to include your reasoning about how the value of each digit was affected by the multiplication. Use words, pictures, or numbers.
Answer:-  The teacher gave 3200.4 and said to multiply with 10. If any number has to multiply with 10 which has decimal value and the value get higher
Actual decimal number has least value so its get higher value when multiplied by 10. Before the value mutliplied  by 10 is show below:
320.04 x 10 = 3200.4

Answer:- A microscope has a setting that magnifies an object so that it appears 100 times that means we have to multiply the insect size with 100.
Insect size is 0.095 x 100 = 9.5 which means the insect appears 9.5 times larger from its actual size.  9.5 cm of size the insect represents its size through
microscope.

Answer:- The value of 6 in (a) is tenth position when we dividing it by 100 it changes its quotient and becomes less value because
when the number is in right of the decimal it has less value. Likewise, when the value is dividing it with 1000 its value becomes 0. something. When we divide any number with any number its gradually decreases and distribute its value to the dividing number.

Question 3.
Researchers counted 8,912 monarch butterflies on one branch of a tree at a site in Mexico. They estimated that the total number of butterflies at the site was 1,000 times as large. About how many butterflies were at the site in all? Explain your thinking, and include a statement of the solution.
Answer:- There are 8912 monarch butterflies on one branch of a tree and they have estimated total was 1000 times large so we have multiplied that with 1000 then will get the total no. of butterflies of all branches of a tree

Monarch Butterflies of a tree in Mexico = 8912
The Estimated butterflies at the Site                  = 1000
Therefore, The total No. of butterflies at the site           = Monarch Butterflies of a tree in Mexico x The Estimated butterflies at the Site
= 8912 x 1000
= 89,12,000

Question 4.
A student used his place value chart to show a number. After the teacher instructed him to divide his number by 100, the chart showed 28.003. Draw a picture of what the place value chart looked like at first.

Explain how you decided what to draw on your place value chart. Be sure to include reasoning about how the value of each digit was affected by the division.
Answer:-  The teacher gave 2800.3 and said to divide with 100. If any number has to divide with 100 which has decimal value and the value get lower
Actual decimal number has  value highest so its get lowest value when divide by 100. Before the value divided  by 100 is show below:
2800.3 ÷ 100 = 28.003

Question 5.
On a map, the perimeter of a park is 0.251 meters. The actual perimeter of the park is 1,000 times as large. What is the actual perimeter of the park? Explain how you know using a place value chart.
Answer:-
The perimeter on the map is 0.251 and the actual perimeter is 1000 times larger i.e., 0.251 x 1000 = 251
So the actual perimeter of the park is 251. We have multiplied the number with actual size of the perimeter.
The teacher gave 3200.4 and said to multiply with 10. If any number has to multiply with 10 which has decimal value and the value get higher  Actual decimal number has least value so its get higher value when multiplied by 10. Before the value mutliplied  by 10 is show below: 320.04 x 10 = 3200.4
