Question

why we have taken 3 and 6 lcm here... the person who explains in detail and step by step will be marked as brainlist...​

Answer 1

Answer:

you have taken a LCM for it since the denominator is one for the number 6 but we need 3 to add or subtract it so we multiply 3 to the denominator of the number 6 since we are multiplying 3 In the denominator we should also multiply it ( the number 3) in the numerator so we get a answer 18 and makes all the terms the like terms so we can add or subtract them
