Percent as decimal move decimal to the left {ex. 0.026 = 0.0026}move from right to left if number has no decimal {ex. 526% = 5.26} drop decimal Decimal to percent move decimal right{ex. 0.954 = 95.4%} move decimal from left to right if number has no decimal{ex. 705 = 70,5000%} any additional zeros can be dropped{ex. 0.0063 = 0.63%} be sure to add % Percent as a fraction or mixed number make percent a fraction over 100{ex. 15% = 15/100} Simplify fraction is possible{ex. 15% = 15/100[divide both sides by 5] = 3/20} if percent is converted and fraction is improper, convert fraction to a mixed fraction and simplfy if possible{ex. 725% = 725/100= 7 25/100 {divide both sides by 25] = 7 1/4} if percent is a decimal, move decimal but add same number of zeros in demominator{ex. 1.45% = 1.45/100 = 145/10000 [divide both sides by 5] = 29/2000} Fraction to percent use long division then convert decimal to percent ( moving to right){ex. 6/25 = 25/6(divide) = 0.24(move decimal) = 24%} Solving Equation is/of = %/100 Simple Interest I = p*r*t p = principler = rate of interest ( decimal)t = time in yearsI = interest Tax tax = taxrate * subtotal (decimal)subtotal = cost + tax Commission commission = total sales * commission rate (decimal) Discount discount = price * discount rate (decimal)sales price = original price - discount Authorregishouse ID112629 Card SetMath 035 Chap 7 DescriptionMath 035 chapter 7 quiz Updated2011-10-30T14:19:15Z Show Answers
