Answer:
we shall convert first the angle in radians to degrees for convenience. The conversion is equal to 108 degrees. In this case, this is a second quadrant angle. The supplement angel is 180 - 108 equal to 72 degrees which is equal to 2 pi/5 . The complement is the same as the supplement
Change the division to multiplication through the reciprocal of the number being divided.
As mixed number:
7/12 times 5/9 equals 35/108. It is automatically in simplest form.

Answers
an easy common denominator is 60 bc 15*4=60 and everything else can equal 60 too so: 6/60+ 15/60+ 12/60+ 8/60 = 41/60 (you only add the numerator numbers) usually you would reduce the end result too but 41 is a prime number so you cant

Following the MDAS rule, where it is necessary to do multiplication or division processes first (whichever of the 2 is encounter first in the equation) before proceeding to addition and subtraction, the expression can be solved, and is done as follows:
