A job can be done by a man in 4 hours, while a boy can do the same job in 8 hours. The man works alone for 1 hour and is then joined by the boy to help him complete the job. After making the corresponding statement, answer the following. Part 1: If T represents the total work and "x" represents the time that the boy works, identify the fraction of the work that the man (H) and the boy (M.) do.

Let's represent the total work as T and the time the boy works as x. Since the man works alone for 1 hour, he completes 1/4 of the job in that time. This means the fraction of work done by the man (H) is 1/4. When the boy joins, he works for x hours. Since the boy can complete the job in 8 hours, he completes x/8 of the job. This means the fraction of work done by the boy (M) is x/8. Therefore, the fractions of work done by the man and the boy can be represented as follows: Fraction of work done by the man (H): 1/4 Fraction of work done by the boy (M): x/8
