Consider the number line below. Using what you know about fractions and whole numbers on number lines, what fractions could be used to represent the whole numbers on this number line? Explain your reasoning.

Fraction on a number line is a visual mathematical representation of fractions. It is done by plotting the given fraction(s) on the number line where the section or the distance between two integers is divided into equal parts which are equal to the denominator of the given fraction.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
