Answer= 40%

40% of call are for air conditioners
1/5 of calls are for heaters

First, lets convert 1/5 into a decimal, and then a percent value.

1/5=0.20=20%

20% of calls are for heaters

100% represents the amount of service calls Mike receives. 

100%-40%-20%=
100%-60%=40%

40% of the service calls Mike receives are other calls.
