When one of the numerator or denominator is negative integer then they are said to be Negative Rational Number. Let's see some examples. Example: -25⁄27, 15⁄-17etc. 1. If both the numerator and denominator of a rational nu… See more

1. Every integer is a rational number but every rational number is not an integer. E.g. 7⁄9 is a rational number and 9 ≠ 0 but 7⁄9 not an integer. E.g. -7⁄9 is a rational number and 9 ≠ 0 but -7⁄9 not an integer. 2. Every natural nu… See more

Before comparing the rational numbers, we must remember the following points: 1. Every positive rational number is greater than 0 and every negative number. 9⁄5 > 0, 9⁄5 > -3⁄2 2. Every negative rational number is less tha… See more

When the denominators are equal: 1. By keeping the denominators same simply add the numerators. 2. Simplify the result if possible. Example 1. Add 2⁄5 and 3⁄5 Solution. 2⁄5 + 3⁄5 = (2+3)⁄5 = 5⁄5 = 1 Example 2… See more
