Maria is adding a shelf to her bookcase. The piece of wood she has for her shelf is 30 1/2 inches long . The other shelves are each 27 1/4 inches long. How much longer is the piece of wood than the other shelves

3 1/4

Step-by-step explanation:

Length of other book shelves = 27 1/4

Difference between the length gives how much longer the piece of wood is than the other book shelves :

30 1/2 - 27 1/4

61 /2 - 109 /4 = (122 - 109) / 4

(122 - 109) / 4 = 13 /4

13 /4 = 3 1/4
