Fractional parts of a whole are those parts of a whole that cannot be expressed as a whole number, but are smaller than the whole itself. It can be thought of as the "missing piece" of a whole, representing the leftover when we divide the whole by a specific part.
Comparison:
Equal fractions: Two fractions are equal if they represent the same part of a whole. For example, 1/2 and 2/4 are equal fractions because they represent the same amount of "missing" pieces.
Unequal fractions: Two fractions are unequal if they represent different parts of a whole. For example, 1/3 and 2/6 are unequal fractions because they represent different "missing" portions of the whole.
Sum:
Adding fractions with the same denominator: When adding fractions with the same denominator, we simply add the numerators together. For example, 1/2 + 1/4 = 3/4.
Adding fractions with different denominators: Adding fractions with different denominators requires finding a common denominator and then adding the numerators. For example, 1/3 + 2/6 = 11/12.
Examples:
Equal fractions: 1/3 = 2/6 (both represent 2/6 of a whole)
Unequal fractions: 1/4 ≠ 2/8 (1/4 represents 25% of a whole, while 2/8 represents 50%)
Adding fractions with the same denominator: 1/2 + 1/4 = 3/4
Adding fractions with different denominators: 1/3 + 2/6 = 11/12
By understanding the concepts of equal fractions, unequal fractions, and adding fractions with the same and different denominators, students can master the topic of fractional parts of a whole
