Parralezation question. Computer Architecture question.

Consider a workload that is 25% parallelizable. lf machine A has 1 computational units and machine B has 72 computational units, what is the performance of machine A relative to machine B on this task? ________ Consider a workload that is 79% parallelizable. What is the maximum speedup that can be achieved through parallelization (relative to pure serial processing). __________
