Last Saturday, Jay spent 6 hours playing games, studying and talking with his friends. he spent 2/5 of the time playing games and 1/2 of the time studying. How many minutes did he spend talking with his friends?

Respuesta :

(1 - (2/5 + 1/2)) x (6 x 60)
(1 - (4/10 + 5/10)) x 360
(10/10 - 9/10) x 360
1/10 x 360 = 36
so he spend 36 minutes talking with his friend
