How do you simplify (3pi)/2 +pi/4? Algebra Properties of Real Numbers Addition of Rational Numbers 1 Answer Alexander Jul 10, 2016 We can make use of the property a/b + c/d = ((a*d)+(b*c))/(b*d) Therefore, (3pi)/(2) + (pi)/(4) = (12pi + 2pi)/(8) =(14pi)/(8) Since both 14 and 8 are divisible by 2, we can simplify further and write (14pi)/(8) = (7pi)/(4) Answer link Related questions How do you add rational numbers?
