Fraction to decimal conversion
Fraction to decimal conversion can be very confusing. I learned to do this in class this week and it really is not as bad as you may think. This conversion all has to do with where you need to move the decimal to make the problem right. You need to ask yourself: "do I move it to the left or right?" There are many types of fractions you might encounter to convert into decimals. These might include proper fractions, mixed fractions, and improper fractions. http://www.learningwave.com/chapters/decimal13/basics/convert.html You may look at the few examples I provided and look at what I did. Look above. Use this website above to help you.
Fractions and decimals represent the same things. They are numbers that are not whole. Please use this website to help you better understand how to convert fractions to decimals. whole.http://webmath.com/fract2dec.html

Decimal Addition
To add decimals, you must write one above the other with their decimal points lined up, like this: look above.
What I learned this week, is simple steps to remember when adding decimals. First, you need to write down the numbers, one under the other, with the decimal points lined up. Next, put in zeros so the numbers have the same lenth. Last, add normally, remembering to put the decimal point in the answer.
Where one decimal doesn't have digits that the other one does, you put in zeroes, like this: look above.
Now, it's easy! You just add the two numbers as you would two whole numbers, with carries if necessary, but you keep track of where the decimal point goes and put it in the result right under the decimal points in the two numbers being added, like this: look above.
