So how many of 5/8 wood pieces out of a 4 5/8 board
let's make the board size into a improper fraction so 8*4+5 = 37
so the board is 37/8
how many times can 5/8 go into 37/8
37/8 / 5/8
"Keep, change, flip" (for division of fractions)
keep the first number, change the sign into multiplication, and flip the last fraction
37/8 * 8/5
That is 7 2/5
Only 7 full 5/8 feet pieces of wood can be cut from a board that is 4 5/8 feet long (remainder 2/5)
Hope this helps :)
