Converting Fractions to Percents

Converting Fractions to Percents

 

 

To convert a fraction to a percent you divide

 the numerator by the denominator.

 

Example: 1/4 1 ÷ 4 = 0.25 

 

Then you move the decimal place two place over to

 the right or multiply by 100 and you get 25%.

 

 

 

Another way to do it is to find what the

 

denominator can be multiplied by to equal 100.

 

Example:

1/4 x 25/25 = 25/100

Then it becomes 25%. 

 

                                                                                              

 Converting Fractions to Mixed Numbers 

 

To convert a mixed number to a percent you make

 the fraction an improper fraction.

 

Example: 2 1/2 then you muliply the whole number by  

                                   

 the denominator and add the numerator so you get 5/2.

 

Next you divide 5 into 2 and you get 0.4.

 

Now you move the decimal two places over to the right and you get 40%.

 

 

 

 WikiPedia’s Information on Mixed Numbers

 

A mixed number is the sum of a whole number and a proper fraction. For instance, you could have

 

 two entire cakes and three quarters of another cake. The whole and fractional parts of the number

are written right next to each other: 2 + 34 = 234.

 

An improper fraction can be thought of as another way to write a mixed number; in the "234"

 

example

 

above, imagine that the two entire cakes are each divided into quarters. Each entire cake contributes

 

44 to the total, so 44 + 44 + 34 = 114 is another way of writing 234.

 

 

A mixed number can be converted to an improper fraction in three steps:

 

 

1.   Multiply the whole part by the denominator of the fractional part.

 

 

2.   Add the numerator of the fractional part to that product.

 

 

3.   The resulting sum is the numerator of the new (improper) fraction, and the new denominator is

 

the same as that of fractional part of the mixed number.

 

 

Similarly, an improper fraction can be converted to a mixed number:

 

 

1.   Divide the numerator by the denominator.

 

 

2.   The quotient (without remainder) becomes the whole part and the remainder becomes the numerator of the fractional part.

 

 

3.   The new denominator is the same as that of the original improper fraction.

What is a Fraction?

Fraction–noun 

 

a. a number usually expressed in the form a/b.

b. a ratio of algebraic quantities similarly expressed.

1. Mathematics. Where Did I get this awesome definition?

What is a Percent?

Percent–noun 

 

1. Also called per centum. one one-hundredth part; 1/100.

 

Percent is from the Latin adverbial
phrase per centum meaning “by the hundred.” The Latin
phrase entered English in the 16th
century. Later, it was abbreviated per cent. with a final period.
Eventually, the period was dropped
and the two parts merged to produce the modern one-word form
The two-word form per cent is still used occasionally,
but its use is diminishing. The percent sign (%) is used chiefly in scientific, tabular, or
statistical material and only with numerals preceding it: 58%.
In the senses “rate or proportion per hundred” and “proportion in general”
and percentage are frequently interchangeable.
With a preceding number, only percent occurs (a 16 percent decline);
with no preceding number, either occurs,
but percentage is much more common: a
certain percentage (or percent) of the land.

A really good draft, with good information, but not quite finished. Some of your page is really hard to read. Use Word or some other program to check the spelling and grammar then copy your text back to your page. Break your title into a couple of pieces so that it fits on smaller screens.
