Kayla wants to give a third of a pie to each of her 25 relatives. She has already baked 6 pies. How many more pies will she need to bake so that each relative can have a third?
$$\left({\frac{{\mathtt{1}}}{{\mathtt{3}}}}\right){\mathtt{\,\times\,}}{\mathtt{25}} = {\frac{{\mathtt{25}}}{{\mathtt{3}}}} = {\mathtt{8.333\: \!333\: \!333\: \!333\: \!333\: \!3}}$$
She needs 8 and a bit pies altogether so she will need to bake 9-6=3 more :))
