Answer:
62 1/4 = 62.25
Step-by-step explanation:
Turn the improper fraction into a mixed number then divide as an equation.
62 x 4 = 248
248 + 1 = 249.
Put the 249 over the 4 and divide.
249/4 = 249 ÷ 4 = 62.25
Let x, y, z ∈ C, the set of complex numbers.
By definition of ○,
(x ○ y) ○ z = (x + y - 2i) ○ z
… = (x + y - 2i) + z - 2i
… = x + y + z - 4i
and
x ○ (y ○ z) = x ○ (y + z - 2i)
… = x + (y + z - 2i) - 2i
… = x + y + z - 4i
so (x ○ y) ○ z = x ○ (y ○ z), which means ○ is indeed associative under C.
