Question

how to subtract two rational numbers
​

Answer 1

Answer:

Keep the first number the same, change the subtraction sign to an addition sign, and change the second number to its opposite. Remember to find a common denominatorwhen adding or subtracting fractions.

Answer 2

Answer:

Imagine that u have two rational nos. = 3/4  and 1/3 and u have to subtract this-

so, first take LCM of Denominators that is   3 and 4 = 12(LCM of 3 and 4)  

            next multiply the no. 3 and 4 to make it 12 . Like we will multiply the denominator 3 with 4, as we are multiplying the denominator so we have to also multiply 4 with numerator according to the concept. So, other side that is 3/4,  we have to also multiply both denominator and numerator by 3. Now,          3*3/4*3 - 1*4/3*4

               =    9/12 -  4/12

              =            5/12

                       

                                 

                                                                               

Step-by-step explanation:

It simlpy  means that we have to do denominator equal by taking LCM of denominator and solve it.
