0.65 is the correct one if not up there try 0.45 other possible one 
Step-by-step explanation:
A rational number is defined as any number which can be expressed in fractional p/q of two integers, where 'p' is the numerator and 'q' is the denominator. 'q' can never be zero. A rational number can also be expressed as a terminating decimal. So, when 0.25 is added in 0.45 it becomes 0.65 which is rational.

Answer:
He is bisecting the angle BAC.
Step-by-step explanation:
First he puts the compass point at point A and draws 2 small arcs at D and E.  Then he places the compass point at D and then at E to form the 2 arcs that cross between the  2 line segments AB and AC.
The bisector is the line he can draw between A and the crossed arcs.
