Xavier's dining room table was unstable because one leg was shorter than the others. He placed a 7/8 inch thick piece of wood under the short leg, and it became even with the other legs, which are 18 3/4 inches long. How many inches long was the short leg before Xavier added the wood?

math 
Ms. Sue,
Subtract 7/8 from 18 3/4
