Question

how many lawns can you mow with one gallon of gasoline if you maintain the rate of 1/2 gallon of gasoline per 1/4 lawn mowed

Answer 1

I think the answer is 4 gallons to mow the lawn
1/2 gallons = 1/4
1 gallons = 2/4
1 1/2 gallons = 3/4
2 gallons = 4/4

Answer 2

`(1)/(2)` lawn

Explanation:

The rate of
`(1)/(2)` gallon of gasoline per
`(1)/(4)` lawn mowed.

We will solve it by unitary method.

∵
`(1)/(2)` gallon of gasoline is used to mow
`(1)/(4)` lawn.

∴ 1 gallon of gasoline is used to mow =
`((1)/(4))/((1)/(2))`

=
`(1)/(4)` ×
`(2)/(1)`

=
`(2)/(4)`

=
`(1)/(2)` lawn

you can mow
`(1)/(2)` lawn with one gallon of gasoline.
