30.  0.25 + 0.25 + 0.25 + 0.25  = _________?
                         0.25

=  4 (0.25
       0.25

= 4 *Ans.

31. 0.0088 ÷ 0.22 = ________?

To start dividing, you have to make the divisor 0.22 a whole number by moving the decimal point 2 places to the right. Doing this will also move two decimal point for the dividend 00.0088.

0.22 is now 22 and 0.0088 is now 0.88

       0.04 
22 | 0.88
       0     
          88
          88
            0

therefore, 0.04 *Ans.


32. (0.15 x 0.37) + (0.85 + 0.63) + (0.15 + 0.63) + (0.85 + 0.37) = _______?

= [(0.15 + 0.63) + (0.85 + 0.63)] + [(0.15 x 0.37) + (0.85 + 0.37)]

= [0.63 (0.15 + 0.85)] + [0.37(0.15 + 0.85)]

= [0.63 (1)] + [0.37(1)]

= 1 *Ans.

33. Which of the following best approximate 68 / 0.17 = ____?

To start dividing, you have to make the divisor 0.17 a whole number by moving the decimal point 2 places to the right. Doing this will also move two decimal point for the dividend 68.

0.17 is now 17 and 68 is now 6800

=6800 / 17

= 400 *Ans.

34. The decimal from of 11/6 is ______?

11 
     6

= 1.83 *Ans.

35. 5/9 of what number is 435 ?

 5  x N = 435
 9

N = 435 ( 9 )
                5

N = 783 *Ans.
