In a basket, $\frac{7}{9}$ of all the apples are red. There are 28 red apples. How many apples are green in the basket?

Step-by-step solution

1. Let $t$ be the total number of apples in the basket.
2. The statement gives $\frac{7}{9}t=28$ because 7/9 of the apples are red.
3. Solve for $t$ by multiplying both sides by $\frac{9}{7}$: $t=28\times \frac{9}{7}$.
4. Compute $t=36$ apples in total.
5. The number of green apples is $t-28=36-28=8$.
