The Second, At the playground, there are ten bicycles and tricycles. If the total number of wheels is twenty-four, how many tricycles are there?

The third,  If it takes five dolphins five minutes to eat five fish, how many minutes would it take four dolphins to eat four fish?

The fourth, An upholsterer is putting new fabric on the back of a chair. The size of the fabric is 27 inches × 27 inches. The upholsterer uses tacks all along the edges of the square so that there are twenty-eight tacks on each side of the square. Each tack is the same distance from the neighboring tacks.

Sixth, Errol, a teacher at the local elementary school, likes to use chalk. He just bought a pack of sixteen sticks. When a stick is three-quarters gone, it gets too small for him to use, so he stops using it. When he has enough of these small pieces to make another stick of the original size, he joins them together and adds them back into the box as a new stick. If Errol uses one piece of chalk each day, how many days would his box of sixteen last?

Seventh, Tim owns a mason company and was hired to build a brick house. The entire house can be built in thirty-one days with five masons. Ten days after they started building the house, Tim hired ten more masons to get the house built quicker. How many more days are required to finish the house?
