Subtraction of Rational Numbers
Subtraction of two Rational Numbers can be done using the following step-by-step method where subtraction of 1/3 and 2/5 is explained.
Step 1: Find the common denominator (LCD) for both the rational number. i.e.,
Common denominator for 3 and 5 is 15.
Step 2: Convert both the rational numbers to equivalent fractions with the common denominator. i.e.,
1/3 = (1 × 5)/(3 × 5) = 5/15
2/5 = (2 × 3)/(5 × 3) = 6/15
Step 3: Subtract numerators of equivalent fractions obtained in step 2. i.e.,
5/15 – 6/15 = (5 – 6)/15 = -1/15
Step 4: Simplify the resulting fraction if possible. i.e.,
-1/15 is already in its simplest form.
Therefore, 1/3 – 2/5 = -1/15.
Rational Numbers: Definition, Examples, Worksheet
Rational Numbers are numbers written in terms of the ratio of two integers, where the denominator is not zero. In maths, Rational numbers are a type of real numbers that can be written in the form of p/q, where q ≠ 0. Any fraction is a rational number provided its denominator should not be zero.
Examples of Rational Numbers include 12/21, 34/2, -22 etc. In other words, a rational number is any number that can be written in the form of a/b, where a and b are integers and b is not equal to zero.
