I am having a problem understanding adding and subtracting fractions with different denominators ​

How on earth may I help you?

Step-by-step explanation:

Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles.[2]:1.1 It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science.

Given two unlike fractions where the denominators are NOT the same. Step 2: Make the denominators the same by finding the Least Common Multiple (LCM) of their denominators. Step 4: Now, add or subtract the “new” fractions from step #3. Always reduce the answer to its lowest terms.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
