Question

Gia spends 2/5 of her money on a shirt she then spends 4/9 of her remaining money on a pair of shoes what fraction of her money is left

Answer 1

5/5 will be a whole, when it comes to 5ths, since she spent 2/5 of her money, 5/5 - 2/5, she has left 3/5 of the whole then.

then she spent 4/9 of her 3/5 leftover, how much is 4/9 of 3/5? well, is just their product,
`\bf \cfrac{4}{9}\cdot \cfrac{3}{5}\implies \cfrac{12}{45}\implies \cfrac{4}{15}`
