Let a and b are whole numbers and
b is not 0.
A number a/b is called fraction.
The number a is called numerator, and b is denominator. A fraction is a number that expresses part of a group.
Denominator shows on how many equal parts we divide and numerator shows how many parts we take.
Example 1: Becky, Merry and John want to divide a chocolate. What part of the
chocolate will they take?
What part of the chocolate will the girls take?
The children divide the chocolate on three parts. So everyone takes 1/3 from the whole chocolate.
The girls are two so they will take two parts of the devided chololate in math language they will take 2/3 from the chocolate.
Example 2: How many are the yellow solders from all soldiers?
Example 3: What part of the apples are missing?
Propery I: All hatched parts from the circles are half(1/2) of the circles and they are equal to 1/2, 2/4 and 3/6. But they all represents half of the circles so 1/2 = 2/4 = 3/6
The fraction 2/4 is result of 1/2 when we multiply the numerator and the denomerator of the fraction by 2. From 3/6 => 1/2 when we devide the numerator and the denomerator by 3. Let's a, b and c are whole numbers, and b and c are not 0.
Property II: Every two fractions with equal denomerators the bigger fracrion is with the bigger nomerator. If a, b and c are whole numbers and c is not 0:
|, if a > b|
Property III :
Every two fractions with equal nomerator the bigger fraction is with the smaller denomerator.
If a, b and c are whole numbers, b and c are not 0.
|, if b < c|
