To convert a fraction into a percentage, first convert the fraction into a decimal by dividing the numerator by the denomenator.  Then, to find the percentage equivalent of a decimal, simply move the decimal (if there is none, remember that there is always an implied decimal after the one's digit) to the right twice:

To convert a fraction into a percentage, first convert the fraction into a decimal by dividing the numerator by the denominator.  Then, to find the percentage equivalent of a decimal, simply move the decimal (if there is none, remember that there is always an implied decimal after the one's digit) to the right twice.  Don't forget to round your answer.  The best answer is:

This problem is merely asking us to convert the eaten fraction of the pizza into a percent. This can be easily solved for by thinking of a whole pizza as being 1. This would mean a whole pizza could be represented by the fraction . Because  of the pizza remians, if we subtract this from , we should be able to solve for the fraction of the pizza that was consumed. 

Therefore,  of the pizza was eaten. This is the fraction we must convert into a percent. In order to do so, we must first convert this into a decimal. As a decimal we can multiply by , which will yield our percent value. 

Therefore, 31% of the pizza was eaten. 

This problem is merely asking us to convert the remaining fraction of the pie into a percent. This can be easily solved for by thinking of a whole pie as being 1. This would mean a whole pie could be represented by the fraction . Because  of the pie has been consumed, if we subtract this from , we should be able to solve for the fraction of the pie that is left over. 

Therefore,  of the pie remains. This is the fraction we must convert into a percent. In order to do so, we must first convert this into a decimal. As a decimal we can multiply by , which will yield our percent value. 

Therefore, 57% of the pie remains. 

To convert a fraction into a percentage, first convert the fraction into a decimal by dividing the numerator by the denominator.  

Then, to find the percentage equivalent of a decimal, simply move the decimal (if there is none, remember that there is always an implied decimal after the one's digit) to the right twice. In other words multiply the decimal by one hundred.

Don't forget to round your answer.  

Thus, the answer is:

To convert a fraction into a percentage, first convert the fraction into a decimal by dividing the numerator by the denominator.  

Then, to find the percentage equivalent of a decimal, simply move the decimal (if there is none, remember that there is always an implied decimal after the one's digit) to the right twice. In other words multiply the decimal by one hundred. Don't forget to round your answer.  

Thus, the answer is:

To write  as a percent, we simply multiply it by 100.  

We get

and we can simplify the 5 and the 100, leaving us with

When we multiply, we get

Therefore,  written as a percent is 80%.

To convert the fraction to a percentage, first we need to convert it to a decimal. We need to get the denominator to be equal to . Or,

What can we mulitiply  by to get ? We can find this by dividing  by ,

We can then multiply this value by the numerator to find the percentage,

We can do this quickly by solving the following equation for ,

This can be done by multiplying both sides by ,

As long as we do the same thing to both sides of the equation we are still OK. Now we can find :

Because this value is what we use to divide by  it is the percent so

To find the percent value, we must take our fraction, convert it to a decimal value and then multiply by :
