Rational Numbers 5/1, 1/2, 1.75, -97/3 ... A rational number is any number that can be written as a ratio of two integers (hence the name!). In other words, a number is rational if we can write it as a fraction where the numerator and denominator are both integers.
A ratio is a comparison between two numbers and it is described as a fraction. If x and y are any two numbers, then the ratio of x to y is $\frac{x}{y}$ , $(y \neq 0)$.ow to Calculate Ratio. Example: The ratio of girl to boy in a class is 12:16. To simplify the ratio we can make the numbers into smaller ratios so as to compare easily. This can be done by dividing the ratio by same number on each side.
