Jumbled Sentences and Words   Jumbled Sentences Sentences have been divided into parts. The parts are named P, Q, R and S. Rearrange the parts P, Q, R and S to form meaningful sentences. Let us look at some examples:  

•                      Example 1

P:  sings                                     Q:  she                R:  very                                     S:  sweetly   (a) PQRS                                   (b) QPRS (c) RQPS                                   (d) PRSQ   Ans. (b) She sings very sweetly.

Factors and Multiples   Introduction We have studied about the operations on numbers, in this chapter, we will study two important terms, that is, ?factors? and ?multiples?. They are related to the operations of multiplication and division.   Factors Factors of a number is the number, which divides the given number completely. If a, b, c, d ?. are factors of ?m? then ?m? will be exactly divisible by a, b, c, d?.   How to Get Factors of a Number To find all possible factors of a number, we have to find all the numbers, which divide the given number exactly.   Rules of Divisibility (i)         The numbers which have 0, 2, 4, 6, or 8 at the unit place is divisible by 2. Ex: 24545666, 69965654, 5484542130 are divisible by 2.   (ii)        If sum of digits of more...

Factors and Multiples   Introduction We have studied about the operations on numbers, in this chapter, we will study two important terms, that is, 'factors' and 'multiples'. They are related to the operations of multiplication and division.   Factors Factors of a number is the number, which divides the given number completely. If a, b, c, d ?. are factors of 'm' then 'm' will be exactly divisible by a, b, c, d?.   How to Get Factors of a Number To find all possible factors of a number, we have to find all the numbers, which divide the given number exactly.   Rules of Divisibility (i)         The numbers which have 0, 2, 4, 6, or 8 at the unit place is divisible by 2.

 Fractions   Fractions Fraction is a number, which in used to represent the part of a whole. It is expressed in the form of \[\frac{P}{Q}\] where P and Q are natural numbers. The upper part of the fraction is called numerator and the lower part is denominator. For \[\frac{5}{9}\] is a fraction, where 5 is numeration and 9 is denominator.

•     Example:

Represent the shaded part of the figure as a fraction.             Solution: \[\frac{1}{4}\]   Like Fraction The fractions, which have the same denominators are called like fractions.

•   Example:

\[\frac{5}{17},\frac{8}{17},\frac{12}{17},\frac{19}{17}\] are like fractions   Unlike Fraction The fractions, which do not have the same denominators, in other words, the fractions with different denominators are called more...

 Operation on Fractions   Operation on the Fractions In the previous chapter, we have studied about the fractions. In this chapter we will study operations on the fractions, like addition, subtraction, multiplication and division on fractions.   Addition of Fractions Make the denominator of fractions same by multiplying a suitable number of the numerator and denominator of both fractions. The common denominator is the denominator of the resultant fraction and addition of numerators is the numerator of the resultant fraction.  

•        Example

Add \[\frac{12}{16}\] and \[\frac{13}{16}.\] Solution:             \[\frac{12}{16}\,+\,\frac{13}{16}\,=\,\frac{12+13}{16}\,=\,\frac{25}{16}\]  

•       Example

Add \[\frac{10}{9}\] and \[\frac{9}{10}.\] Solution: \[\frac{10}{9}\,=\,\frac{10}{9}\,\times \,\frac{10}{10}\,=\,\frac{100}{90}\]             \[\frac{9}{10}\,=\,\frac{9}{10}\,\times \,\frac{9}{9}\,=\,\frac{81}{90}\] Therefore, their sum = \[\frac{10}{90}\,+\,\frac{81}{90}\,=\,\frac{100+81}{90}\,=\,\frac{181}{90}\]   Subtraction of Fractions Make the denominator of each fraction more...
