Given that
There are some parts and we have to solve them to get the answers.
Explanation -
(a). 51 pounds of seeds can be planted on 8 acres of land.
It can be written as
8 acres = 51 pounds---------------(i)
and we have to find the pounds of seed per acre. So dividing the eq(i) by 8
1 acre = 51/8 pounds of seed
1 acre = 6.375 pounds of seeds.
After rounding off to the nearest hundredth we have
1 acre = 6.38 pounds of seed
So 6.38 pounds of seeds will be planted per acre.
(b). The rent for the usage of 8 hours for a bike is $29.
It can be written as
$29 = 8 hours----------------(ii)
and we have to find the hours he gets per dollar. So dividing eq(ii)by 29 we have
$1 = 8/29 hours
$1 = 0.275 hours
After rounding off to the nearest hundredth we have
$1 = 0.28 hours.
So 0.28 hours will be given for 1 dollar.
