Solution:

UPQ31-1.   Arrange the digits 5, 3, 7, 6, 9 and 2 to form the smallest

possible 6-digit even number. The place value of the

digit 7 in this smallest number is  ___________.

(1) ones

(2) tens

(3) hundreds

(4) thousands

235796   7 hundreds

UPQ31-2.  Express 4 9/20 as a decimal.

(1) 4.09

(2) 4.45

(3) 4.2

(4) 4.9

4 9/20 = 4 + 9/20

= 4 + 0.45

= 4.45

UPQ31-3.   Multiply 0.08 by 1000. What is the answer?

(1) 0.8

(2) 8

(3) 80

(4) 800

0.08 × 1000 = 8 × 10 = 80

UPQ31-4.    A number becomes 834 000 when it is rounded off to the

nearest thousands. The number is  _____________.

(1) 832 600

(2) 833 400

(3) 833 600

(4) 834 600

834 000 – 832 600 = 1 400

834 000 – 833 400 = 600

834 000 – 833 600 = 400

834 600 – 834 000 = 600
