Chapter Rational Number Exercise 9.1 Hello Learners...... Let us all resume from the previous class. Q8. Fill in the boxes with correct symbol out of >, <, = (i) -5/7     🗆    2/3 Step 1      -5/7 and 2/3    {make equivalent fraction} Step 2      -5 X 3        and    2  X 7                 7 X 3                3 X 7 Step 3       -15/21   and 14/21   {do comparison} Step 4   -15/21   < 14/2  {positive number is always greater than negative no} Finding difficult, let try one more..... (ii)  -4/5     🗆     -5/7 Step 1    -4/5 and -5/7  {make equivalent fraction} Step 2      -4 X 7       and      -5 X 5                 5 X 7                 7 X 5 Step 3      -28/35   and  -25/35    {do comparison} we know that -28 < -25 Step 4 therefore       -28/35  <  -25/35             hence    -4/5 <  -5/7 Let us try one more....... (iii) -7/8    🗆   14/-16 Step 1        -7/8  and 14/-16     {make equivalent fraction} Step 2 

Chapter Rational Number Lesson 4 Exercise 9.1 Hello Learner, At the end of today's blog, you will be able to  (i) Compare the rational numbers. (ii) solve rational numbers in simplest forms. (iii) write rational numbers in ascending and descending order. Lets begin from the previous class where we have solved math problems of writing equivalent rational numbers and representing them on number line. Important Instructions 1. Do neat and clean work. 2. Make rough column in page.  3. No over writing. Utilize your next period in completing the pending work Before we start with new math problem click on the line to recapitulate the basis of rational number https://www.youtube.com/watch?v=J9ToEVrlD0g Let us all start.................. Q6. Which of the following pair represent the same rational number? (i) -7/21 and 3/9 Step 1             -7/21   =   -1/3             {reduce to lowest term}                        3/9   =   1/3                {reduce to

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    

Good morning boys, Today we going to see how to represent a rational number on a number line. You can now Attempt on Ex 9.1 on page 183 in your copies. I will now attempt Q4. (i) and you can do the rest on your own. Now Attempt Q4. (ii), (iii), (iv) on your own in your copies. Question 5 has been done below for your reference. Now re-do Question 5 in your copies on your own. Thankyou boys Have a nice day.

REMINDER FOR ALL..... *We at St Columba's School, are ready to take the next step - and move towards using Google Classroom as a tool to enhance the teaching learning environment. *This shift involves the school giving each student a unique email address, which he will need to setup ( the teachers will assist him in doing the same). This email will facilitate each student to interact with his teachers. * The student should use this email ID only for: -interacting with  teachers on school /subject related matters -keep the words and expressions as he would- if he  were interacting with us as a Columban student -use the facilities connected to this email ID only for google meets organised with the permission of a teacher  -he should have a copy of the permission given ( when and by which teacher and for what purpose) -do not access any of the other facilities connected with this email address unless he first seeks the permission of a teacher (He should have a copy of th
