Fraction Fun!

Nothing causes more math anxiety among children and adults than fractions - that is, until they get to algebra! And when an algebra problem contains fractions, look out! The rules for working with fractions can seem inconsistent and confusing. For example, when must you have a common denominator and why? Why should you reduce? Since decimals and percents are just fractions, why bother having all three?
