Answer:
6 acres
6/7 lb left
Step-by-step explanation:
Each 7/8 of a lb is good for 1 acre.
He has 6 lb.
The first step is to see how many amounts of 7/8 lb are in 6 lb.
This is a division problem.
6 / (7/8) = 6/1 * 8/7 = 48/7 = 6 6/7
6 lb is 6 6/7 portions of 7/8 lb.
Since each 7/8 lb is good for 1 acre, he has enough for 6 6/7 acres.
He can plant 6 whole acres.
The remaining seed is 6/7 lb.
