Question 2.
In which number is the place value of the digit 9 ten times as much as the place value of the digit 9 in 410,917?
A. 159,230
B. 305,942
C. 432,691
D. 590,231
Answer:
Given number is 410,917
The place value of 9 is 900.
The place value of the digit 9 ten times as much as the place value of the digit 9 in 410,917 is 900 × 10 = 9000
So, 159230 is the correct answer.
Option A is the correct answer.

Question 3.
Use Tools 5elect all the equations that represent a product of 54,000. Tell what strategy or tool you will use, explain your choice, and then find the answers.
A. 2,700 × 2 =
B. 600 × 90 =
C. 1,800 × 30 =
D. 54 × 104 =
E. 9 × 6 × 103 =
F. (6 × 10) × (9 × 100) =
Answer:
A. 2,700 × 2 = 5,400
B. 600 × 90 = 54,000
C. 1,800 × 30 = 540,00
D. 54 × 104 = 5,40,000
E. 9 × 6 × 103 = 54 x 1000 = 54,000
F. (6 × 10) × (9 × 100) = (60) x (900) = 54,000
Therefore, B, C, E, and F are the correct options.

Question 4.
What number is $$\frac{1}{10}$$ of 5,000? ____
Answer:

Find the unknown exponent.

Question 6.
4 × 10 = 4,000
________
Answer:
let it be ‘a’
so, 4 x 10 x a = 4,000
a = 4000 / 40 = 100
Therefore, the unknown exponent is 100.

Question 7.
7 × 10 = 700,000
_________
Answer:
let it be ‘a’
so, 7 x 10 x a = 700,000
a = 700,000 / 70 = 10,000
Therefore, the unknown exponent is 10,000.

Question 19.
Forty boxes of baseballs weigh a total of 1,200 pounds. How many pounds would 4 boxes of baseballs weigh? How many pounds would 400 boxes of baseballs weigh?
Answer:
Given,
Forty boxes of baseballs weigh a total of 1,200 pounds.
Weight of each baseball box = 1,200/40 = 30
Therefore, Weight of 4 baseball boxes = 4 x 30 = 120 and
Weight of 400 baseball boxes = 400 x 30 = 12,000

Question 20.
The population of the town Val lives in is about 8 × 103. The population of the town Vic lives in is about 6 × 104. Whose town has the greater population? By how many people?
Answer:
Given,
The population of the town Val lives in is about 8 × 103.
The population of the town Vic lives in is about 6 × 104.
The town Vic lives in has a greater population than the town Val lives in. ( 60000 > 8000 )
The difference = 60000 –  8000 = 52,000
Therefore, the difference between the population of the two towns is 52,000.
