<\/span><\/h3>\nAn algebraic expression is an equation that consists of different types of integer constants, variables, and operators. Variables in an expression can take up any value, while constants remain the same.<\/p>\n
Also, there can be any number and type of operators in an algebraic expression, including those that perform addition, multiplication, subtraction, or even division.<\/p>\n
RS Aggarwal Class 7 Maths Solutions has many problems in the exercise section which you can work on to get acquainted with the chapter. The problems get more complex as you progress.<\/p>\n
<\/span>RS Aggarwal Class 7 Solutions Chapter 7: Linear Equations in One Variable<\/span><\/h3>\nLinear equations are algebraic expressions that have one or more variables. In this chapter, you will understand various concepts related to linear equations while also learning how to solve them.<\/p>\n
<\/span>RS Aggarwal Class 7 Solutions Chapter 8: Ratio and Proportion<\/span><\/h3>\nThe ratio is the relationship between two numbers in terms of how many times the first number contains the second number. If the two ratios are equal, then they are in proportion.<\/p>\n
So, in this chapter, you will get problems with ratio and proportion. You can solve the exercise problems present at the end of the solutions to get a better understanding of the chapter.<\/p>\n
<\/span>RS Aggarwal Class 7 Solutions Chapter 9: Unitary Method<\/span><\/h3>\nIn the Unitary Method, you solve a problem by finding the value of one of the single units and multiplying that value to get the required result.<\/p>\n
You apply this method in everyday activities. For example, when you buy vegetables from a vendor, you can use the Unitary Method to find the total cost. You can solve a few exercise problems to get a better understanding of the chapter.<\/p>\n
<\/span>RS Aggarwal Class 7 Solutions Chapter 10: Percentage<\/span><\/h3>\nThe percentage of a number is a part of the number out of every 100. For example, if 20 people watch TV out of every 100, then the percentage of people who watch TV is 20. You represent percentage using the symbol \u2018%.\u2019<\/p>\n
You may have come across the concept in your everyday life. Many surveys use the concept of a percentage to ascertain how many people use a particular product or brand. You should solve as many problems as you can to get a better idea about the chapter.<\/p>\n
<\/span>RS Aggarwal Class 7 Solutions Chapter 11: Profit and Loss<\/span><\/h3>\nThe concept of profit and loss depends on the cost price and the selling price of an article or any other material. Don\u2019t forget to go through and solve the exercise problems so that you will get a better idea about the concept of profit and loss.<\/p>\n
<\/span>RS Aggarwal Class 7 Solutions Chapter 12: Simple Interest<\/span><\/h3>\nSimple Interest is one of the easiest techniques that you can use to calculate the interest accrued on loans. In this chapter, you will come across various problems related to estimating the interest of loans.<\/p>\n
<\/span>RS Aggarwal Class 7 Solutions Chapter 13: Lines and Angles<\/span><\/h3>\nA line extends in two directions. To make it easier to estimate the length of a line, we consider that the line extends only in one direction.<\/p>\n
Also, when two or more lines extend from the same point, an angle forms between them. By using suitable geometrical tools, we can calculate the degree of the angle formed between two or more lines.<\/p>\n
<\/span>RS Aggarwal Class 7 Solutions Chapter 14: Properties of Parallel Lines<\/span><\/h3>\nTwo lines are parallel when they are equally apart from each other. For example, a railway track is a parallel line. In this chapter, you will learn about parallel lines and their properties.<\/p>\n
