Hubert's job is to shovel 3/4 of the driveway whenever it snows. If he gets 1/3 of the driveway shoveled right after the snow stops, and does another 1/4 of the driveway after he has taken a chocolate break, what portion of his job has he done?

he has done 1/3 + 1/4 = 7/12
7/12 / 9/12 = 7/9 ths done
