Question

It takes 63 pounds of seed to completely plant a 7 acre field. How many acres can be planted per pound of seed?

Answer 1

0.11 acres can be planted per pound of seed

Solution:

Given that it takes 63 pounds of seed to completely plant a 7 acre field

To find: acres can be planted per pound of seed

Let "x" be the acres which can be planted per pound of seed

Therefore, from given question,

63 pounds of seed = 7 acre field

1 pound of seed = "x" acre field

This forms a proportion and we can solve the sum by cross multiplying

Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction

Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction

Set the two products equal to each other

Solve for the variable

$63 \times x = 7 \times 1\\\\63x = 7\\\\x = \frac{7}{63} = 0.11$

Thus 0.11 acres can be planted per pound of seed
