Transcript: To convert a percentage into a fraction, just divide by 100% Example: 115% 12 1/2% 115/100 25/5÷100 115 ÷ 5/ 100÷5 1/2 x 1/4 =23/20 =1/8 Percentage, or also called per centum, is the rate or proportion per hundered ex., three percent interest. The symbol is % ex., 100%. x%+ x/100 To find a quantity as a percentage of another, write the first as a fraction of the second and multiply by 100% Example: Bob drank half of a 350ml drink 350÷2= 150 150/350 x 100% = 50% To convert a fraction or decimal into percentage, just multiply by 100% Example: 3/5 0.0042 3/5 x 100% 0.042 x100% = 60% =4.2% Simple interest is interest that is calculated each year as a fixed percentage of the original amount borrowed. The fixed percentage is called the interest rate, and is usually written as a percentage per annum, which means per year. Example: Find the interest payable on a loan of $60000 borrowed at 9% p.a. for 4 years. Simple interest change each year is $5400. $ 5400 x 4 = $ 21 600 By: Grace James Converting percentage into fractions & decimals Percentage increase and decrease Converting fractions & decimals into percentages Use this equation, cost price x multiplier = selling price Example: An electrical goods store buys a TV set at a wholesale price. The price of the TV is increased by 25% for sale by the store. Its selling now $550. For what price did the store by the TV set? cost price x 1.25= $550 cost price + $550/1.25= $440 So, the TV set cost the store $440 Simple interest This is a easy method in two steps- 1. Find the size of the increase or decrease 2. Apply the change to the original quantity by addition or subtraction GOAL! Finding percentage of a quantity Percentage What is percentage? Finding the original amount Expressing quantity as a percentage of another To find percentage of a quantity, we convert the percentage to a fraction or a decimal, and then multiply Example: 6% of 150kg 6/100 x 150kg 6/2 x 3kg =9kg
