Changing percentages to decimals, changing decimals to percentage

 In this lesson we're going to do another converting lesson. This time is converting percentages to decimal and converting decimals tom percentages.

  Converting decimals to percentages or converting percentages to decimals is quite easy to do it.
Firstly to change percentages to decimals:
1. you need to divide the numerator from the denominator. 
2. Then move the decimal point to the left twice.

  Second is to change decimals to percentage, there are two methods you can choose.
1. Multiply decimal from 100.
2. Move the decimal point to the right, twice.


1. Our first example is "Convert 32% to a decimal."
32% = 32/100.
= 0.32

2. Second example is "Convert 253% as decimal."
253% = 253/100 = 2.53.

3. Third and last example is " Convert 78 1/5% to a decimal."
78 1/5% = 78.20/100 = 0.782.


1. Our first example in converting decimals to percentage is " Convert 0.34 as a percentage."
We move the decimal point to the right, or you do 0.34 multiplied by 100.
0.34 = 34%, 0.34 x 100 = 34%.

2. Second example is "Convert 7.52 to percentage."
Same as this, you move the decimal point to the right or do the multiplication.

  7.52 = 752% or 7.52 x 100 = 752%.

3. Third and example is "Convert 0.875 to percentage."
0.875 = 87.5% or 87 1/2% or
0.875 x 100 = 87.5% or 87 1/2%.

4. Forth and last example is "Convert 0.0525 to percentage."
0.0525 = 5.25% or 5 1/4% or
0.0525 x 100 = 5.25% or 5 1/4%.
