A hash table with $200$ buckets currently stores $112$ keys. What is the load factor of the hash table?

Please, use a point as a decimal separator

EntA separate$-$chaining hash table with $9$ buckets uses the hash function $f(x)=x\%9.$ If the hash table stores the keys

$76,253,5,142$

what is the length of the longest chain in the hash table?
