Re: dividing by decimals

Vanessaluis12,
What is it that you want to know about dividing by decimals?

I shall try to explain with a few examples.

(i) 12/0.5 -> Shift one place to the right the decimal in the numerator as well as denominator. You get 120/5. By actual division, you can find out the answer is 24.

(ii)36.5/0.5 -> Shift one place to the right the decimal in the numerator as well as denominator. You get 365/5 and by actual division, you get the answer 73.

(iii) 2500/0.125 -> In order to make the denominator a natural number, you'd have to shift both the numerator and denominator three places right of the decimal. Thus you get 2500000/125. On actual division you get 20000.

The important thing to do is convert the denominator into a natural number, and when you do so, necessary adjustments would also have to be made in the numerator.
