Solving Algebra word problems is useful in helping you to solve earthly problems.

While the 5 steps of Algebra problem solving are listed below, this article will focus on the first step, Identify the problem.

Solving word problems is an art of transforming the words and sentences into mathematical expressions and then applying conventional algebraic techniques to solve the problem.

They may involve a single person, comparing his/her age in the past, present or future.

They may also compare the ages involving more than one person.

$0-150=90$$ Then we find out how many percent this change corresponds to when compared to the original number of students $$a=r\cdot b$$ $=r\cdot 150$$ $$\frac=r$$ $[[

They may also compare the ages involving more than one person.

$$240-150=90$$ Then we find out how many percent this change corresponds to when compared to the original number of students $$a=r\cdot b$$ $$90=r\cdot 150$$ $$\frac=r$$ $$0.6=r= 60\%$$ We begin by finding the ratio between the old value (the original value) and the new value $$percent\:of\:change=\frac=\frac=1.6$$ As you might remember 100% = 1.

Since we have a percent of change that is bigger than 1 we know that we have an increase.

To find out how big of an increase we've got we subtract 1 from 1.6.

You can solve many real world problems with the help of math. To solve problems with percent we use the percent proportion shown in "Proportions and percent".$$\frac=\frac$$ $$\frac\cdot =\frac\cdot b$$ $$a=\frac\cdot b$$ x/100 is called the rate.Break the problem down into smaller bits and solve each bit at a time.First, we need to translate the word problem into equation(s) with variables.
