adding and subtracting rational numbers rules Adding and subtracting rational expressions is similar to adding and subtracting fractions Recall that if the denominators are the same we can add or subtract the numerators and write the result over the common
The rules of addition and subtraction of integers are also valid for rational numbers Recall that rational numbers are numbers that can be represented as fractions where a is the numerator of the fraction and b is the denominator of the fraction However b must be not eqaul to zero In order to add and subtract rational numbers using a number line To add start at the first number and move to the second number to subtract start from the second number and move to the first number Write your answer Adding and subtracting rational numbers examples Example 1 adding negative numbers using counters

Problem 1 Add The numerator should be expanded and simplified The denominator should be either expanded or factored 5 x x 3 4 x 2 Explain Least common denominators Numerical fractions Sometimes the denominators of two fractions are different but have some shared factors Follow the rules below for adding the rational numbers Examples on adding rational numbers in fractional form Examples on adding rational numbers in decimal form Examples on adding rational numbers in real life situations Frequently asked questions Rational number
Addition and Subtraction We will cover Addition and Subtraction in one go as they are the same method Before we add or subtract the rational numbers should have the same bottom number called a Common Denominator The easiest way to do this is to Multiply both parts of each number by the bottom part of the other Adding and subtracting rational numbers A rational number is a number that can be written as the ratio of two integers To add or subtract rational numbers use the same rules for signs as for integers To add or subtract two rational expressions each fraction must have the same denominator Example frac 1 3 frac 1 6 Step1

The rules for adding and subtracting integers apply to all rational numbers The sum of two rational numbers for example 1 4 3 can be found on the number line by placing the tail of an arrow at 1 and locating the head of the arrow 4 3 units to the right to arrive at the sum which is 3 3 To add rational numbers follow these steps Make sure both addends have the same form They should both be fractions or both be decimals If the numbers are fractions write them to have common denominators Look at the signs of the addends to determine how to solve If the addends have the same sign add their absolute values
