A fraction describes a part of a whole, with a numerator and denominator, and can represent ratios, proportions, and unit rates. Simplifying fractions by reducing common factors is important, and fractions with equal numerators and denominators always equal 1.
A fraction represents a part of a whole and is written with a numerator over a denominator, such as 1/5.
This means if you divide something like a pie into 5 pieces, taking 1 of those pieces would be 1/5 of the pie. When dealing with complex fractions, common factors in the numerator and denominator can be reduced to simplify the fraction.
A fraction with the same quantity in the numerator and denominator equals 1, because they cancel each other out, even if they are in different units such as 100 cm/1 m, which is a conversion factor.
Understanding fractions can also be intuitive, such as knowing that two-thirds of a pie is more than half.
Moreover, fractions can also be related to ratios, proportions, and unit rates that help compare quantities.
