c. $$15 \ vegetable \ packs$$

$$ 25 \ vegetable \ packs$$
Work Step by Step
1. 1 variety pack = 3 packs of vegetable.
$$20 \ variety \ packs \times \frac{3 \ vegetable \ packs}{1 \ variety \ pack} = 60 \ vegetable \ packs$$
$$4.667 \ variety \ packs \times \frac{3 \ vegetable \ packs}{1 \ variety \ pack} = 14 \ vegetable \ packs$$
$$0.25 \ variety \ pack \times \frac{3 \ vegetable \ packs}{1 \ variety \ pack} = 0.75 \ vegetable \ pack$$
2. $$30 \ beef \ packs \times \frac{1 \ variety \ pack}{3 \ beef \ packs} = 24 \ variety \ packs$$
$$3 \ beef \ packs \times \frac{1 \ variety \ pack}{3 \ beef \ packs} = 1 \ variety \ pack$$
$$10 \ beef \ packs \times \frac{1 \ variety \ pack}{3 \ beef \ packs} = 3.333 \ variety \ packs$$
3. $$30 \ chicken \ packs \times \frac{1 \ variety \ pack}{6 \ chicken \ packs} \times \frac{3 \ vegetable \ pack}{1 \ variety \ pack}= 15 \ vegetable \ packs$$
$$2 \ chicken \ packs \times \frac{1 \ variety \ pack}{6 \ chicken \ packs} \times \frac{3 \ vegetable \ pack}{1 \ variety \ pack}= 1 \ vegetable \ pack$$
$$25 \ beef \ packs \times \frac{1 \ variety \ pack}{3 \ beef \ packs} \times \frac{3 \ vegetable \ pack}{1 \ variety \ pack}= 25 \ vegetable \ packs$$
