1 Fractions are broken parts of whole integers or items

2 Fractions have numerators above their denominators

3 Fractions are separated by the solidus line

4 Fractions can be multiplied and divided

5 Fractions need a common denominator to be subtracted or added

6 Fractions less than 1 are common fractions

7 Fractions greater than 1 are improper fractions

8 Fractions less than 0 are negative fractions

9 Fractions can be equivalent as 1/2 = 4/8

10 Fractions can be simplified as 3/15 = 1/3

11 Fractions can be dissimilar as 3/8 is not 5/8 but they add up to 1

12 Fractions can be converted into percentages as 3/4 = 75%

13 Fractions can be converted into decimals as 3/4 = 0.75

14 Fractions can form part of a mixed number as in 3 and 3/4

15 Fractions are rational numbers

16 Fractions can't be formed from Irrational Numbers

17 Fractions were used by the ancient Romans to a limited extent as 1/2 = S

18 Fractions can be converted into scientific notation as 1/1,000,000 = 1.0*10-6

19 Fractions are used in algebra: if 1/a+1/b = c then a+b = abc

20 Fractions increase when divided and decrease when multiplied

What are at least fifteen facts about fractions?

Why do you clear fractions in a linear equation?

Multiply every term in the equation by a common denominator of all the fractions. The least common denominator (if different) will result in smaller numbers that you then have to work with but it is not essential that you use it.


What is the least common multiple of fifteen and sixty?

fifteen


What is the least common denominator of two fractions?

The least common denominator is the least common multiple of the denominators of the fractions.


Is 1 to 1 least or greatest on a list of fractions?

Greatest on a list of proper fractions, least on a list of improper fractions.


What is the least common denominator for fifteen and twenty?

There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions. Even if you converted your numbers (x) to their fraction equivalents (x/1), the LCD will always be 1.


How do you find fractions from least to greatest?

you have to compare the common fractions


What do you call listing fractions from least to greatest or greatest to least?

Listing the fractions is ascending (or descending) order.


How do you sort fractions least to greatest?

Get each fraction to have a common denominator, and then sort the fractions from least to greatest based on the numerators.


What is the least common denominator of twelve and fifteen?

There is none because the Least Common Denominator (or LCD) refers to the Least Common Multiple (LCM) of the denominators of two or more fractions or mixed numbers. Even if you converted your whole numbers (x) to their fraction equivalents (x/1), the LCD would always be 1.


Fractions least to greatest?

It's impossible to list all fractions, because there are no least or greatest fractions. In addition, between any two fractions, there's another fraction (for example, the average of the two functions).


What is the LCD for fractions?

The LCD for fractions is the LCM (least common multiple) of all of the denominators.
