First, we need to figure out how many sections of 1/8 acre are in 1 acre.
1 acre = 8 sections of 1/8 acre
It takes Robbie 1/5 hour to mow 1/8 acre, so to mow 1 section (1/8 acre), it will take him:
1/5 hour
To mow 8 sections (1 acre), it will take him:
8 x (1/5) hour
= 8/5 hour
Therefore, it will take Robbie 1.6 hours to mow the full acre.
1 acre = 8 sections of 1/8 acre
It takes Robbie 1/5 hour to mow 1/8 acre, so to mow 1 section (1/8 acre), it will take him:
1/5 hour
To mow 8 sections (1 acre), it will take him:
8 x (1/5) hour
