How to Convert Fractions into Decimals

Complete the division problem. If a pattern of repeating numbers appears, you can can notate the pattern by placing a bar over the numbers in the decimal.http://www.purplemath.com/modules/percents2.htm#Fraction_to_Decimal Decimals can also be rounded off using mental math. Increase the value of the number to be rounded if the number to the right is 5 or higher and make no change to the number if the value is smaller than 5.http://cstl.syr.edu/fipse/decunit/roundec/roundec.htm

Proper Nouns

In the popular board game Scrabble, the rule has always been that proper nouns were not permitted. However, on April 6, 2010, the manufacturer of the game, Mattel, announced that new version of the game, named Scrabble Trickster, would allow the players to use proper nouns. This opens the avenue up to a whole new group of words that fall under the criteria described above. The new game upset many Scrabble purists, who played the game under old rules for decades. http://www.cbsnews.com/stories/2010/04/06/entertainment/main6368179.shtml

How to Convert Fractions

Now that we have converted our raw test score of 19/20 into the decimal .95, we move the decimal to the right to create a percentage. When moving from decimals to percentages, we always move the decimal two places to the right. The decimal .95 becomes the percentage 95.% and because there are no numbers to the right of the decimal, it can be dropped to give us 95%. Hopefully, this use of grades as an example of how to convert fractions will help you remember to move the decimal two places to the right in order to get the percentage.

The Quadratic Formula: Satisfying Conditions

Now you have a quadratic equation with all terms to one side and a solution of zero. You must identify your coefficients (a, b, and c) for use in the quadratic formula.http://www.youtube.com/watch?v=EG9_-1strY4  

In the equation x^2 - 3x + 5 = 0, a is, in fact, the number 1. Coefficient b is -3 and c is 5.http://www.youtube.com/watch?v=EG9_-1strY4  

Once you have identified the coefficients, you may use them in the quadratic formula to find out the value(s) of x.http://www.purplemath.com/modules/quadform.htm

Punctuation

Punctuation has been around since ancient Rome and Greece, when it was used as a public speaking aid. Speeches were prepared in writing and punctuation was used to let the speaker know when to pause, and for how long. The period was the longest pause, the comma was the shortest, and the colon was somewhere in between.http://grammar.about.com/od/punctuationandmechanics/a/PunctuationHistory.htm

William Caxton, an English printer, liked to use the forward slash (/), which he used primarily as a comma. After him, playwright Ben Johnson began to explain the uses for other punctuation marks, such as the comma, parenthises, period, and question mark in his book, The English Grammar. There is no "father" of punctuation, however. It has changed greatly from its primitive youth, and over the years has been modified to become what it is today: an important tool for writers.http://grammar.about.com/od/punctuationandmechanics/a/PunctuationHistory.htm

How to Multiply Fractions

Multiplying fractions is easier than adding or subtracting them because you don't need to have a common denominator. First multiply the numerators and the denominators and then reduce the fraction. 

For example, for this equation: 











Multiply the two numerators to find the top number of the answer. Then multiply the denominators to find the botton number. 










If applicable, reduce the fraction to find your final result. To do this, find the largest number that can be divided into both the numerator and denominator.
