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.
10* (1/5)
= 10/5
= 2
The final answer is 2~
This is what you do. You multiply 1/10 and 40. Like this: 1/10 x 40/1
