Explanation:

These are basically 3 problems, so I won't explain two items for every one of your 13 similar questions. Here's the explanation for every 3 cases asked in your questions... and the answers. All you have to do is replace the numbers in the explanations for the ones in each other question asking the same thing.

To express a fraction in percentage, you simply have to put the fraction with a denominator of 100..., for example:

`(1)/(20) * (5)/(5)  = (5)/(100)`

So, 1/20 is 5%.

`(1)/(2) * (50)/(50)  = (50)/(100)`

And 1/2 is 50%

To express a percentage as a fraction, you take that percentage and place it over a denominator of 100 and you simplify, like this:

`(12.5)/(100) = (1)/(8)`

`(30)/(100) = (3)/(10)`

To convert a decimal number to a fraction, the easiest way is to express this number up to the 2nd decimal... then take that as a %.

Examples:

0.2 you can say 0.2 = 0.20... so it's 20 hundredths, or 20 per 100... so 20%

0.375, it's already expressed in more than hundredths, so you simply move the dot 2 spots right to get 37.5%

what is 1/20 as a decimal and a percentage: 5% (see above)

what 1/10 as a decimal and a percentage : 10% (save as above)

what 12 1/2% as a decimal and a percentage: 12.5%, it's already as a percentage, if you mean as a fraction... 1/8 (see above)

what is 0.2 as a fraction and a percentage: 1/5 and 20% (see above)

what is 25% as a decimal and fraction: 0.25 and 1/4

what is 30% decimal and fraction : 0.3 and 3/10

what is 1/3 as a decimal and percentage : 0.33 and 33%

what's is 0.375 as a fraction and percentage : 3/8 and 37.5%

what is 0.4 as a fraction and percentage : 4/10 and 40%

what is 1/2 as a decimal and percentage : 0.5 and 50%

what is 0.6 as a fraction and percentage : 3/5 and 60%

what is 0.625 as a fraction and percentage: 5/8 and 62.5%

what is 66 1/2% as a decimal and fraction: 0.665 and 665/1000, 133/200
