Answer:
0.5185 kg are needed to make 2 kg of cat food

Chicken bones and chicken pieces in the ratio 20:7
This means that [tex]\frac{20}{20 + 7} = \frac{20}{27}[/tex] of the total weight is of bones and [tex]\frac{7}{27}[/tex] is of pieces.
What weight of chicken pieces is needed to make 2 kg of cat food?
7/27 of 2kg. So
(7/27)*2 = 14/27 = 0.5185 kg
0.5185 kg are needed to make 2 kg of cat food
