Simple Proportion-ssdao

In our daily life, by learning ratio and proportion many a times we .pare two quantities of the same type. Thus, in convinced situations, .parison by division makes better sense than .parison by taking the difference. The .parison by division is the Ratio. We denote ratio-using symbol ":". If two ratios are equal, we state that they are in proportion and use the symbol ":" or "=" to equate the two ratios. Simple Proportion Definition and Example Problems: Definition of proportion: If two ratios are not equal, then we state that they are not in proportion. In a statement of learning proportion, the four quantities involved when taken in order are known as respective terms. First and fourth terms are known as extreme terms. Second and third terms are known as middle terms. a: b = c : d Examples of simple proportion: Simple problem1: Are the ratios 30g: 40g and 48 kg: 72 kg in proportion? Solution: 30 g: 40 g =30 / 40 = 3 / 4 = 3: 4 48 kg: 72 kg = 48 / 72 = 4 / 6 = 4: 6 So, 30: 40 = 48: 72. Therefore, the ratios 30 g: 40 g and 48 kg: 72 kg are in proportion, i.e. 30 : 40 :: 48 : 72. The middle terms in this are 40, 48 and the extreme terms are 30, 72. Simple problem 2: Do the ratios 30 cm to 4 m and 20 sec to 5 minutes form a proportion? Solution: Ratio of 30 cm to 4 m = 30: 4 100 (1 m = 100 cm) = 3: 40 Ratio of 20 sec to 5 min = 20: 5 60 (1 min = 60 sec) = 20: 300 = 1:15 Since, 3: 40 " 1: 15, therefore, the given ratios do not form a proportion. Simple problem 3: Sam works as a dental hygienist. Last week Sam made $500 for 20 hours of work. How many hours must Sam work in order to make $800? Solution: Sam works as a dental hygienist $500 / 20hours = $800 / x hours 20 hours * $800 = x hours * $500 16000 = $500 x 16000 / 500 = x 32 = x Sam 32 hours work in order to make $800 Practice Problem for Simple Proportion Problems: Practice problem 1: Gabriella bought five cantaloupes for $3.
