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
