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:
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.
