An equation stating 2 ratios are equal?

Propotion


What are 2 ways you can tell that 2 ratios form a proportion?

what are 2 ways you can tell that 2 ratios from a propotion


How do you use proportions?

A propotion is a math method. For example 3 over 100 = x over 50, you crossmultipy both 3 times 50 and 100 times x, then you'll get 150 = 100x, then you have to get x by itself so you divide 100 from both sides and that leaves you with x = 1.5.The proportion in this problem is 3 over 100 = x over 50

For example 3 over 100 = x over 50, you crossmultipy both 3 times 50 and 100 times x, then you'll get 150 = 100x, then you have to get x by itself so you divide 100 from both sides and that leaves you with.(basicly you just cross multiply= 3/100*x/50) Multiply 100 times 50 then make another fraction starting with that answer for 100*50(at the bottom) then multiply that answer times 3.and so you get 1000 over 15000. That can be reduced to 15.


What is the answer for pi?

'pi' is an IRRATIONAL number. This means that its decimal digits go to infinity and the digits are not in any regulr order. Super Duper Computers have calculated 'pi' to more than 50 billion places, and stil going. However, for school work , pi is 3.14, 3.1416, 22/7 These are only approximate values. 'pi' has been known from pre-Classical history . It was found that the circulaference of a circle was always directly proportional to its diameter. The Constant of PROPORTION is 'pi'. 'pi' is the Classical Greek samll /lower case letter 'p' and stands for propotion. The circle equations you should learn in school are ;- C = pi d ( circumference and diamter) C = 2 pi r (circumference and radius) A = pi r^(2). ( Area and radius squared).
