Formula: B PIR Base = Percentage/Rate Rate - the value obtained from the quotient of Percentage and Base commonly expressed in percent Formula: R= P/B Rate = Percentage/Rate Percentage To solve percentage problems, when the rate is express in percent, convert percent 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 =BxR P= (50%) x (50) = (.50) x (50) P= 25 B-50 P=? Therefore 50% of 50 is = 25 2. What is % of 100? Given R= % B= 100 P? Formula P=BxR P= (1/4) x (100) = (0.25) x (100) P= 25 Therefore1/4 of 100 is = 25 3. How much is 100% of 500? Given R= 100% B = 500 Formula P=BxR P= (100%) x (500) = (1) x (500) P= 500 P=?

12:35 E O A alall business math midter... 12. An employee receives 14,500 pesos as his monthly salary. 35% of it will be deducted by his taxes and loans. How much wauld be his take home pay? 13. Only 2/3 of the class of 45 students have secured their admissions slip. How many students do not have admissions slip? 14 The total enrolment is 1,750. 60% of the total enrolments are females. How many male students were enrolled? 15. A candidate needs 50.01% of the voting population to be a majority winner. If the total voting population is 25,000 then how many votes must he have to reach 50.01%? Rate Problems This 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 in percent form. Example: 1. What percent of 50 is 107 Given B = 50 Formula R = P/B R= 10/50 =0.2 P= 10 R=? Since 0.2 is in decimal, but the question asked how many percent, therefore convert 0.2 into percent by moving the decimal point two places to the right and write percent symbol ater the number. Therefore, the answer to the problem is 20%, and therefore 10 is 20% of 50 or 20% of 50 is 10 2. One hundred is what percent of 100? Given B= 100 P= 100 R=? Formuia R = P/B R. 100/100 = 1 Convert 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- 80 P= 100 R=? Formula R= P/B R= 80/100 = 1.25 Convert 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= 100 Formula R = P/B R= 100/BO = 0.08 P= 80 R=? 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= 7 Formula R = P/B R= 7/20 = 0. Convert 0.035 to percent by moving the decimal point two places goi. P= 200 R=? 32/41 therefore the final answer is 3.5% MATH BM Buiness Mathematicaj Moduie RMGumanoy/BRRodrigune Page 31 6 PEXERCISES 3.3: Find the value of R (rate) 5 is what percent of 38? hat percent of 72 is 9?
