Online Ratio And Proportions Tutors

Online Ratio And Proportions Tutors Ratio is the quantitative comparison between quantitates. Proportion is a fixed ratio between two substances. Proportion always maintains a fixed ratio between two fractions. For example, a / b = c / d. It can be written as a : b = c : d. This can also be called as the proportion formula. Proportion in math is defined as the similarity while comparison between two quantities or substances. Example 1: Find the y in the given ratio and proportion 4 : y = 2 : 5. Solution: Here the given proportion is 4 : y = 2 : 5. It can be expressed as a fraction in the form. 4 / y = 2 / 5 Now multiply both sides of the equation by y. This gives 4 = 2 y / 5. Now multiply both sides of the equation by 5. This gives 2 y = 10. Now divide both sides of the equation by 2. So y = 5. Hence the value of y for the given proportion = 5. Example 2: Find the x in the proportion x : 6 = 4 : 3. Solution: Here the given proportion is x : 6 = 4 : 3. It can be expressed as a fraction in the form. This gives, x / 6 = 4 / 3 Now multiply both sides of the equation by 6. This gives 6 (x/ 6) = (4 / 3) (6). x = 24 / 3 = 8. Hence the value of x for the given proportion is 8.
