It is obtained by dividing thePercentage by the Rate.Formula:B PIRBase = Percentage/RateRate - the value obtained from the quotient of Percentage and Base commonlyexpressed in percentFormula:R= P/BRate = Percentage/RatePercentageTo solve percentage problems, when the rate is express in percent, convertpercent to decimal then multiply it to the base. When the rate is expressed in fraction,convert fraction to decimal and then multiply it to the base,Example:1. 50% of 50 is how much?Given R=50%Formula P =BxRP= (50%) x (50)= (.50) x (50)P= 25B-50P=?Therefore 50% of 50 is = 252. What is % of 100?Given R= % B= 100P?Formula P=BxRP= (1/4) x (100)= (0.25) x (100)P= 25Therefore1/4 of 100 is = 253. How much is 100% of 500?Given R= 100%B = 500Formula P=BxRP= (100%) x (500)= (1) x (500)P= 500P=?Theretore 100% of 500 is = 5004. How many 1.5% of 60?Given R= 1.5%B= 60P=?Formula PBXRP= (1.5%) x (60)= (0.015) x (60)P-0.9Therefore 1.5% of 60 is = 0.9PEXERCISE 3.2: Solve the following probiems.1. What is %% of 200?2.

How manymale students were enrolled?15. A candidate needs 50.01% of the voting population to be a majority winner. If thetotal voting population is 25,000 then how many votes must he have to reach 50.01%?Rate ProblemsThis lesson will help yau find the value of (R) Rate in percentage problems and,solve problem involving rate.Rate problem uses the equation or formula R= P/B where the value of R is inpercent form.Example:1. What percent of 50 is 107Given B = 50Formula R = P/BR= 10/50=0.2P= 10R=?Since 0.2 is in decimal, but the question asked how many percent, therefore convert0.2 into percent by moving the decimal point two places to the right and write percentsymbol ater the number.Therefore, the answer to the problem is 20%, and therefore 10 is 20% of 50 or 20% of50 is 102. One hundred is what percent of 100?Given B= 100P= 100R=?Formuia R = P/BR. 100/100= 1Convert 1 to percent by moving the decimal point two places going to the right,therefore the final answer is 100%3. What part of B0 is 100?Given B- 80P= 100R=?Formula R= P/BR= 80/100= 1.25Convert 1.25 to percent by moving the decimal point two places going to the right,therefore the final answer is 125%4. What part of 100 is 80?Given B= 100Formula R = P/BR= 100/BO= 0.08P= 80R=?Convert 0.08 to parcent by moving the decimal point two places going to the right,therefore the final answer is 8%5. Seven is what part of 200?Given B= 7Formula R = P/BR= 7/20= 0.Convert 0.035 to percent by moving the decimal point two places goi.P= 200R=?32/41therefore the final answer is 3.5%MATH BM Buiness Mathematicaj ModuieRMGumanoy/BRRodrigunePage 316 PEXERCISES 3.3: Find the value of R (rate)5 is what percent of 38?hat percent of 72 is 9?What part of % is % ?What part of 95 is 100?Th- -- h eim 4n t een t-- tt5. 700 is what part of 500?6. 800 is what part of 800?7.
