Best Answer

1 Fractions are parts of whole numbers or integers

2 Fractions have numerators above their denominators

3 Fractions have a solidus line that separates numerator from denominator

4 Fractions can be common as for example: 3/4

5 Fractions can be improper or 'top heavy' as for example: 22/7

6 Fractions can form part of a mixed number as for example: 3 and 1/7

7 Fractions can be converted into percentages as for example: 1/2 = 50%

8 Fractions can be converted into decimals as for example: 3/4 = 0.75

9 Fractions can be equivalent: 5/8 = 10/16

10 Fractions need a common denominator when added or subtracted

Fractions that are not equivalent are dissimilar fractions * * * * * The term is used more commonly to refer to fractions whose denominators are different.

It really doesn't matter whichever one you are more comfortable with. fractions are a bit more challenging to convert.

I suggest you take a look at the Wikipedia article on "triangle", or at some similar source. I am sure you can find lots of interesting facts there.

It is sometimes used as a 'friendly' way of indicating that someone is plainly lying, more often to indicate that someone is embellishing the true facts; or in other ways is suggesting more or other things than the plain facts justify.

I can get you started with one: Nobody who knows anything about it calls it "the pi of a circle". Pi is pi.

its just using fractions but not more than once to make other fractions
