You're only supposed to ask one question at at time but here we go:-
1 Fractions are parts of whole numbers or integers
2 Fractions less than 1 are common fractions
3 Fractions greater than 1 are improper fractions
4 Fractions have denominators which are underneath their numerators
5 Fractions are separated by a solidus line such as n/d
6 Fractions that are improper can be changed into mixed numbers
7 Fractions can be changed into decimals
8 Fractions can be converted into percentages
9 Fractions are rational numbers
10 Fractions can not be derived from Irrational Numbers
11 Fractions need a LCD when adding or subtracting them
12 Fractions can be easily multiplied and divided
13 Fractions can be equivalent such as 2/3 = 4/6
14 Fractions can be simplified by finding their HCF
15 Fractions use prime numbers to find the LCM of different denominators
16 Fractions were once used by the ancient Romans to a limited extent
See related question: 'What are 15 or more facts about fractions'
Yes their is an interesting fact about fractions that is you have to know how to do them
it is a odd number
2 over 3
it has a numerator
8/30 and 12/45
16/30 or 17/30, for example.
to make them as simple as possible
15/24 can be simplified to 5/8
16/60 + 21/60
Six over fifteen, two over five.
fractions that can not be simplified any more
There are infinitely many equivalent fractions. Multiply the numerator (top) and the denominator (bottom) of the fraction by any non-zero number. You will have an equivalent fraction.
ten sixteenths, fifteen twenty-fourths, and twenty thirty sixths =)
2/3 and 20/30 ok
its just using fractions but not more than once to make other fractions
In the end of April 2012 or sooner.
1/4 is one quarter or 1 15/16 is one and fifteen sixteens and so on.
Eight over fifteen is. If you could get used to calling those fractions "seven fifteenths" and "one fifteenth", then you'd quickly realize that 7 of anything plus 1 of the same thing is 8 of them.
King Khufu had 24 child fifteen daughters and nine sons. :)
In actual problems, we convert two (or more) fractions so that they have equal denominators.
