DIVIDE DECIMALS Question 2

A decimal is also a percentage(%).
A percentage(%) is a part of 100; the number 1 is 100%, the number 2 is 200%, the fraction 1/2 is 50%.
A decimal is written as:
0.1 or 0.10 or .1 or .10
1 = 1.0 = 1.00 = 100/100 = 100%
0.1 = 0.10 = .1 = .10 = 10/100 = 10%
0.01 = .01 = 1/100 = 1%
0.001 = .001 = 1/1000 = 0.1%
As the decimal point(.) moves to the right the number becomes larger.
As the decimal point(.) moves to the left the number becomes smaller.
The places to the right of the decimal point(.) are place holders for ones, tens, hundreds, etc., just as the place holders for whole numbers such as 1, 10, 100, 1000.


0.2  ÷  0.1  =
Step 1: We can think of the 2 decimals as 2 numbers. First we will move the decimal point to the right as follows:
0.2 becomes 02.0 and 02.0 = 2.0 = 2; 0.1 becomes 01.0 and 01.0 = 1.0 = 1; then we get the following:
      2
1 | 2
      2
      0
Note: When these two decimals are divided, the decimal point(.) in the answer moves to the right.
Step 2: As a proof of our answer we can say:
0.2 = 20/100 AND 0.1 = 10/100 then:
0.2  /  0.1  =  20/100 =  20  x  100 = 20 x 100 = 2000 = 2000/1000 = 2 = 2 = 2.0
                       10/100   100       10     100 x 10    1000    1000/1000     1
Step 3: The answer can also be written as:
2.0 = 2.00 = 2 = 200/100 = 200%
Conclusion: We started out with two decimals and now have a whole number.
0.2  ÷  0.1  =  2.0
