Then x has a expansion of decimal which terminates. 3) Let x =p/q be a rational number, such that the prime factorization of q is not of the form 25, where n, m are non-negative integers. Then, x has a expansion of decimal which is non-terminating repeating (recurring).
In this case, $5,500 minus $5,000. You had an increase of $500. Divide the increase ($500) by the original starting number ($5,000). The resulting decimal, 0.10 or 10 percent, is the percentage increase from last year to this year. The same formula applies to decreases.
