Rational Numbers Blog 2

Good morning boys,

Today we are going to learn equivalent rational numbers.

1. On multiplying the numerator and denominator of a given rational number by the same non zero number, we get a rational number. equivalent to the given number.

2. On dividing the numerator or denominator of a given number by a common divisor we get a rational number equivalent to the given rational number.

3. Thus 2 rational number are said to be equivalent if one can be obtained from the other by multiplying or dividing its numerator and denominator by the same non zero number.

Thus, equivalent rational number are equal.

Thus, equivalent rational number are qual.

Example of equivalent rational number:

Find 4 rational numbers

eg. Find x such that  -3  and  x  all equivalent rational numbers.

                                    8         -24

Soln. -3  =   x  

           8     -24

          -3   =   x 

           8      -24

          -3 x -24 = X x 8

           72     =   x

            8

            9    =    x

Do the following: 

Q1. Find x:

1.  -1  =  8 

      5      x

2.  7  =  x 

    -3      6

3.  16  = -4

      x

4.  -48  = 2

       x

5.  13  = -65 

      6         x 

Ex 9.1 Pg 182 Attempt Q2.[2, 3, 4] (NCERT)

 Attempt Question Q3 {2 and 3}

Attempt  Question 2 to 7.
