A sandbox is 7/9 of the way full of sand. You scoop out 3/7 of the sand which is currently in the box. What fraction of sand (in relation to the entire box) is left in the sandbox?

x = full box

7/9 x  - 3/7 (7/9 x )

7/9 x  - 21/63 x

(49/63 - 21/63 )  x

28/63   of  x is left    (  4/9 ths is left)
