Jack spends 1 and a quarter as long on his homework as Jill. Last week Jill spent 9 and three quarters of a hour on his homework. How long did Jack take??? Write the answer as a mixed number! Thnx!
Jack spent 11 hours on his homework. This is because Jill worked 9 3/4 hours on her work, and since Jack worked 1 1/4 hours more than her. 9 3/4 + 1 1/4 = 11.
