Algebra FractionsAlgebra fractions are proportions
To understand fractions you must however work with them. Moreover, no matter how you see them, all fractions boils down to numbers which you can use for instance by digitizing them in a calculator. These numbers can have decimals or not, can be comprised from 0 to 1 (= proper fractions such as 1/2) or greater than 1 (= improper fractions like 6/3) and be positive or negative. Another very common way of naming fractions is using the word percentage and the symbol %. Finally, you write a fraction in the following way
A number on TOP and a number at the BOTTOM with a line inbetween. The top is also called Numerator, the bottom, Denominator but this is not so important. The numerator is a cardinal number word ("1", "2", "3", etc..), the denominator is a ordinal (sequential) number word ( "third", "forth", "fifth", etc...an exception is "half" which clearly indicate a part of the whole, a (sub)divided unity). This way of writing means the following:
CAREFUL NOW!
One more things. Number like those just described, with a "top" and a "bottom" are called rational numbers, because, as we said, they represent a ratio! But these rational number do no only serve as a representation of a ration. Check here to learn more on rational numbers!
Take pictures of "fractions" around you! Hint: this is a view from my balcony. You can see the roof of the school which my children attend and other houses and trees in the backgrounds.Can you see the "fractions"? The solar panels can be seen as a set of objects. A singular solar panel is divided into equal subparts, the tiny rectagles. There are also other fractions in the main pictures . Which ones? Answer: sʍopuıʍ ǝɥʇ
Conclusions A fraction is something difficult to understand You need to work with them and have a practical experience All fractions are in the ends numbers (digits) that you can enter in a calculator
Now, you can start working with fractions if you like. You can do it by using three ways of looking at them, three exercises: as an area model, a linear model or a set model.
