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
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) = 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? ____
From given data,
1/10 x 5000
5000/ 10 = 500
Therefore, value of $$\frac{1}{10}$$ of 5,000 is 500.

Question 5.
What number is 10 times as much as 40,000? ____
10 x 40,000 = 4,00,000
Therefore, the value of 10 times as much as 40,000 is 4,00,000.

Find the unknown exponent.

Question 6.
4 × 10 = 4,000
________
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
_________
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.

Multiply.

Question 8.

Question 12.  Question 13.  Question 14.  Question 15.  Question 16.  Question 17.  Question 18.
The planet Neptune takes about 165 years to make a complete orbit around the Sun. About how many years does Neptune take to make 18 complete orbits?
Given,
The planet Neptune takes about 165 years to make a complete orbit around the Sun.
For 18 years,
165 x 18 = Therefore, Neptune takes 2970 years to make 18 complete orbits around the sun.

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?
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
