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 × 10^{4} =

E. 9 × 6 × 10^{3} =

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 × 10^{4} = 5,40,000

E. 9 × 6 × 10^{3} = 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:

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? ____

Answer:

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

________

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.

**Multiply.**

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?

Answer:

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?

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 × 10^{3}. The population of the town Vic lives in is about 6 × 10^{4}. Whose town has the greater population? By how many people?

Answer:

Given,

The population of the town Val lives in is about 8 × 10^{3}.

The population of the town Vic lives in is about 6 × 10^{4}.

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.
