**URGENT:** It will take Mr. Warner 15 1/2 hours to install a fence. Each day, he works 1 1/3 hours on the fence. After he finished working on the fence yesterday, he had 3 1/2 hours left to do. For how many days has Mr. Warner worked on the fence?

Respuesta :

He worked for 9days
15 1/2 = 31/2
3 1/2 =7/2

31/2 - 7/2=24/2=12

12 hours+ 3.5 hours =15.5 hours

1 1/3 = 4/3

12/1 divided into 4/3 is the same as
12/1* 3/4 =36/4 =9
