Explanation:

  1. collect like terms. that is the positive and negative terms
  2. 2/3+7/2-5/4
  3. lcm of 3 and 2 is 6 hence 2/3+7/2= 25/6
  4. 25/6-5/4....lcm of 6 and 4 is 12 hence 25/6-5/4=35/12

\sf{3. \ \ Given : (2)/(3) - (5)/(4) + (7)/(2)}

Let us solve the first two fractions : The LCM of 3 and 4 is 12


\sf{\implies (4(2) - 5(3))/(12) + (7)/(2)}


\sf{\implies (8 - 15)/(12) + (7)/(2)}


\sf{\implies (-7)/(12) + (7)/(2)}

LCM of 2 and 12 is 12


\sf{\implies (-7 + 7(6) )/(12)}


\sf{\implies (-7 + 42)/(12)}


\sf{\implies (35)/(12)}


\sf{\implies 2 +(11)/(12)}


\sf{\implies 2 (11)/(12)}

---------------------------------------------------------------------------------------


\sf{4. \ \ Given : ((2 - 7)^2 + 5)/(3)}


\sf{\implies ((-5)^2 + 5)/(3)}


\sf{\implies (25 + 5)/(3)}


\sf{\implies (30)/(3)}


\sf{\implies 10}
