## About fractions

Fraction (origin “fractus”, from Latin means broken) is a part of whole, or any number of equal parts. Fraction is not used only in math, they are used in everyday English and describes how many parts of a certain size there are, for example: three-quarters, one-half. A fraction (example: ) consist of an integer numerator, which is displayed above the line, and non-zero denominator, displayed below the line. Numerator represents a number of equal parts and the dominator (cannot be zero) tell us how many parts make up a unit or a whole. In our example, in the fraction, the numerator one tell us the fraction represents one equal part, and dominator tell us that two parts make up a whole. Fractions can be written without using the numerators and denominators, using the decimals, or percent signs (example: 0,01, 1%). Fractions also can be represented as ratios and divisions.
