UPQ21-1. *Which digit in 8 670 593 is in the ten thousands place? *

* (1) 9 *

* (2) 8 *

* (3**) 7** *

* (4) 6*

UPQ21-2. *What number is 3 hundredths more than 3.8? *

* (1) 3.38 *

* (2**) 3.83** *

* (3) 4.10 *

* (4) 6.80 *

UPQ21-3. *Round off 156 732 to the nearest ten thousand.*

* (1) 160 000*

* (2) 157 000*

* (3) 156 000*

* (4) 150 000*

UPQ21-4. *500 ÷ 1000 = __________.*

* (1) 0.05*

* (4) 20*

Solution:

UPQ21-1. *Which digit in 8 670 593 is in the ten thousands place? *

* (1) 9 *

* (2) 8 *

* (3) **7** *

* (4) 6*

** **8 670 593

70 000 Seventy thousands

UPQ21-2. *What number is 3 hundredths more than 3.8? *

* (1) 3.38 *

* (2) **3.83** *

* (3) 4.10 *

* (4) 6.80 *

3 hundredths is 3/100 = 0.03

1.8 + 0.03 = 3.83 is 3 hundredths more than 3.8

UPQ21-3. *Round off 156 732 to the nearest ten thousand.*

* (1) 160 000*

* (2) 157 000*

* (3) 156 000*

* (4) 150 000*

Number 156 732 to round off to the nearest ten thousand.

56 732 will be 60 000

So, 160 000

UPQ21-4. *500 ÷ 1000 = __________.*

* (1) 0.05*

* (2) 0.5*

* (3) 2*

* (4) 20*

** ** 500 ÷ 1000 = 5 ÷ 10 = 0.5
