Answer:
20 knives
Step-by-step explanation:
the ratio of fork to knives is [tex]\frac{4}{5}[/tex] and their are 16 forks, so we put the ratio of fork and knives equal to number of fork and knives so its:
[tex]\frac{4}{5}[/tex] = [tex]\frac{16}{x}[/tex] We cross multiply
80 = 4x Divide both side by 4
x = 20
we can check too
16/20 if we simplify, its give us 4/5
