In order to turn a decimal into a fraction you must first look at the decimal. If it is .5 it is half of 1 so it is 1/2 as a fraction. Another would be 2.5 it will be 21/2. You can tell all by looking at the decimal this is what makes it easier than solving for the decimal from a fraction. It is a really simple stepped method consisting of only looking at the decimal and knowing how to change it.
To turn a fraction into a decimal you would have to first , turn the fraction into a improper one. Then, you would make it into a mixed number. You would take the turn such as, 2 and 1/4 and turn it into 2.25. Remember this is only to solve a improper fraction. For a non improper fraction such as 2/4 you could see it is 1/2 if simplified. You would then turn it into .5 becuase .5 is half of 1 whole. There is another way. Though it is a longer process it will still work. Such as 2/4 again multiply it by 25 then you get 50/100 which is still 1 half or .5.
I would say that if you go to a resturant that you should use percentages instead of ratios. This is because if you used ratios not only would it be a longer process but it would be very confusing. If you used percentages it would be easier becuase alls you would need to do would be to take all of your purchases prices and turn them into a decimal and add them up and divide them by the total. Ratios you would have to turn them into decimals then ratios then add them up and divide it by the total. With ratios you have a extra step and with percentages you don't. So which would you use?
It is fairly easy and I would like to see who votes for my choise or not. So go to my comments and tell me which one you would do. |
