Jim spoke on the phone with all his friends last weekend.On Saturday he spoke for 3/8 of an hour and on Sunday he spoke for half an hour. During that time spent, he spoke to liam for 1/8 of an hour .What fraction of the time Jim spent talking with his friends did he spend talking to Liam ?

(1/8)/(3/8 + 1/2)
(1/8)/(7/8)
1/8 * 8/7
1/7
