Fractions, Number Lines, and Order

Motivation Question

What is wrong with the following sample advertisement statement?

For one day only, save,, and even more‼! This is a sale you cannot miss‼!

 

Each fraction value is less than the previous value, , but the ending "and even more" implies that each fraction value is becoming greater in value. The statement is a common mistake that many people make when using fractions. Here, the order of the fractions in the statement is based on the value of the denominator and not on the true value of the fraction. The statement should be, For one day only, save  ,, and even more‼! since the advertisement is implying that on some items a person can save more than half the listed price.
