Question

defination of ratio and proportion
in a brief way ​

Answer 1

Ratio: The relative size of two quantities expressed as the quotient of one divided by the other; the ratio of a to b is written as a:b or a/b.

Proportion: An equality between two ratios.

Answer 2

Answer:

Step-by-step explanation:

Ratio: A ratio is a comparison of two or more numbers that indicates their sizes in relation to each other. The ratio a is to b is the fraction $\frac{a}{b}$, written as a:b.

Eg: The ratio 3 is to 5 is the fraction $\frac{3}{5\\}$, written as 3:5.

Proportion: Four numbers (a, b, c, d) are said to be in proportion if the product of a & d and b &c are equal. We can also say that 4 numbers(a, b, c,d) are in proportion if the product of the extremes(a and d) and product of the means(b and c) are equal.

Eg: 22:33::42:63 are in proportion because the product of the extremes (22*63=1386) and the product of the means(33*42=1386) are equal.

Hope this helps!!
