Every row of five people has one more person, and every row of seven people has two more people.

( 1)5÷7=0.。 . . . 5,

∴(5×6)÷7=4.。 . . . 2.

(2)7÷5= 1.。 . . 2,

(7×3)÷5=4.。 . . 1

∴ Over there is 5×6+7×3=5 1 (person)

More realistic. What do you mean, there are three more people in each team with five people? )
