A fraction is part of a whole. It is divided into a numerator and a denominator.
Fractions can be shown using a diagram. A pizza could be used as a whole with 8 peices (slices) to show how fractions work.
Equivalent fractions are fractions that represent the same amount but have different numerators and denominators.
Comparing fractions is determining which fraction is larger or smaller.
A percentage is a way of expressing a number as a fraction of 100. To convert fractions to percentages divide the numerator (number on the top) by the denominator (number on the bottom) and multiply by 100.
