Fractions are types of integers and are used to represent a part of the whole. They are represented in the format of “p/q” where the “p” part is called the Numerator and the “q” part is called the Denominator. Decimal numbers are fractions with the divisor as 10 or multiples of 10. In this chapter, we will discuss multiplication of fractions, reciprocal of a fraction, multiplication and division of decimal fractions.

__Chapter 3 Data Handling__

This chapter is part of statistics in which we will be dealing with mean and median of the organised data. Arithmetic mean is a number that lies between the highest and the lowest value of data. Mode refers to the observation that occurs most often in a given data. We will also see the use of various types of graphs and charts.

__Chapter 9 Rational Numbers__

A rational number is a number that can be written in the form p/q, where p and q are integers and q ≠ 0. A rational number is said to be in its standard form if its numerator and denominator have no common factor other than 1, and its denominator is a positive integer. We will see operations of rational number such as addition, subtraction, multiplication and division of rational numbers.

__Chapter 12 Algebraic Expressions__

Expressions that contain constants and variables, or just variables, are called algebraic expressions. A term that contains only a number is called a constant term. The constants and the variables whose product makes a term of an algebraic expression, are called the factors of the term. Students will learn operations on Algebraic Expressions and their applications.

__Chapter 13 Exponents and Powers__

An exponent or power is a mathematical representation that indicates the number of times that a number is multiplied by itself. If a number is multiplied by itself m times, then it can be written as: a x a x a x a x a...m times = am. Here, a is called the base, and m is called the exponent, power or index. We will see laws of exponents and solve various problems on it.

#### What do you mean by Isometric Sketches?

Isometric dot sheet is such a sheet which divides the paper into small equilateral triangles made up of dots or lines. To draw sketches in which measurements also agree with those of the solid, we can use isometric dot sheets.

#### What is exterior angle of a triangle and its property?

An exterior angle of a triangle is formed, when a side of a triangle is produced. At each vertex, we have two ways of forming an exterior angle. If a side of a triangle is produced, the exterior angle so formed is equal to the sum of two interior opposite angles.
