of the grandmother's lawn Dan can mow per gallon.
Option C
<u>Solution:</u>
Given that, mowing
uses
gallon of gas.
To find: The fraction of the lawn can Dan mow per gallon
According to unitary method,
gallon of gas is required to mow
of lawn that is 
Therefore, 1 gallon of gas will be required to mow 

Therefore, one gallon will be enough to mow
of lawn.
Unitary method:
The unitary method is a technique to solve a problem by finding the value of a single unit first, and then finding the required value by multiplying the single unit value. In essence, this method is used to find the value of a unit from the value of a multiple, and hence the value of a multiple.
What is it? can you write out the problem.
