These fractions both have the same denominators so we can add them without having the equate them first. The only thing you have to do is add the numerators (7 and 5), and keep the denominators the same. 7     5            12 -- + ---    =    ------ 12    12         12 When you simplify 12/12 it becomes 1. The second piece of wood is 1 foot long
