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

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 = ____?
