Answer:

3frac{5}{9} cups of milk and frac{1}{3} cups of oil for 8 people .

Step-by-step explanation:

Cups of milk for 6 people = 2 frac{2}{3} =frac{8}{3}

Cups of milk for 1 people = frac{frac{8}{3}}{6}=frac{4}{9}

Cups of milk for 8 people = frac{4}{9} times 8= frac{32}{9}

Cups of oil for 6 people = frac{1}{4}

Cups of oil for 1 people = frac{frac{1}{4}}{6}= frac{1}{24}

Cups of oil for 8 people = frac{8}{24}=frac{1}{3}

Hence 3frac{5}{9} cups of milk and frac{1}{3} cups of oil for 8 people .
