Question

What are the three ways to represent a proportions

Answer 1

Answer: GoodMorning: ) ✨ According to proportion, if two sets of given numbers are increasing or decreasing in the same ratio, then the ratios are said to be directly proportional to each other. Proportions are denoted using the symbol '::' or '='. For example, 2:5 :: 4:8 or 2/5 = 4/8.

Two values x and y are said to be directly proportional to each other when the ratio x:y always remains the same. Example : If we buy two pen for 50 Rs. It will cost us 100 Rs for four pen. Two values x and y are said to be inversely proportional to each other when the ratio x:y1 always remains the same.

Answer 2

Answer: Product of extremes (numbers on extreme edges) = product of means i.e., ad = bc

a, b, c, d,…. are in continued proportion means, a:b = b:c = c:d

a:b = b:c then b is called mean proportional and b2 = ac

The third proportional of two numbers, a and b, is c, such that, a:b = b:c

d is fourth proportional to numbers a, b, c if a:b = c:d
