Andre is cutting fence boards from a large piece of wood 10 1/4

yards long. Each board needs to be 4/5
yard. How many whole, equal-sized boards can he cut from this piece of wood?

To find out how many whole, equal-sized boards Andre can cut from the large piece of wood, we need to divide the length of the wood by the length of each board.

10 1/4 yards = 10 + 1/4 yards = 10 + 0.25 yards = 10.25 yards

4/5 yard = 0.8 yard

Now, we can divide the length of the wood by the length of each board:

10.25 yards / 0.8 yard = 12.8125

So, Andre can cut 12 whole, equal-sized boards from this piece of wood.
