Rational Expression Word Problems Rational Expression Word Problems A rational expression can be defined as an expression through which user can easily represent the calculative problem in the form of two integers. In mathematics as we know that rational numbers can be consider as a part of number system which is capable of representing the integer value in the form of fractional form. Here the fractional form refers to representing the integer values in the form of denominator and numerator. Suppose there are two integers given that are p and q, now they can be represented in the form of rational number as p / q. In the given notation the word ‘p’ can be consider as the value of numerator in the rational number and the word ‘b’ refers to the value of the denominator in the rational number. When we deal with the rational number then it is mandatory that the value of the denominator of the rational number should not be equal to zero. Know More About Column Method Addition Worksheet

As in above notation given that the word ‘p ’ and ‘q’ are denoting the rational numbers. So, the value of ‘q’ must not be equal to zero. Here we are going to discussing about the rational expression. Expression is a part of algebra that is used for representing the mathematical problem into a word problem. In the rational expression word problem, the mathematical operations can easily be performed to solve the problems that are related to the calculative mathematics. In the rational expression word problems user has main task to perform the conversion of mathematical expression into the rational expression word problem. When user going to solving rational expression word problem then he needs to consider some of the issues that are given below Step a ) user need to carefully analyze the mathematical problem to solve them. Step b ) After that labeled the different entities of expression by different variable names. Step c ) now read the question line by line and arrange them in their particular order with their mathematical operation. Step d) In the last user able to solve the rational expression by applying the various concept and properties of algebra. In the below some of the rational expressions examples are given to understand the concept of rational expression word problem. Read More About Column Addition Worksheet

Example A: There are two painter hired for a house. The owner of the house gives the task to both painters to paint the house. If the first painter complete their work in the eight hours and other painter complete their work in ten hours. Now you need to calculate what will be the total time taken by both painters when they complete their work together? Solution: the above question can be solved by applying the rational expressions steps that are used for solving the rational expression word problems. To solve we perform the analysis of given question in which describe that there are two painters completing their task. Now we need to convert the given rational expression into rational number format. Let’s show you below: The first painter complete their task with the rate of = 1 / 8 hours, in the same aspect The second painter complete their task with the rate of = 1 / 10 hours If in case when both performing the work of painting the house together then the total time will be taken by them is : Work rate of first painter + work rate of second painter 1 / 8 + 1 / 10 => so, total time will be taken= 5 + 4 / 40 = 9 / 40 hours.
