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

Answer:

$\frac{1}{2}$ lawn

Step-by-step explanation:

The rate of $\frac{1}{2}$ gallon of gasoline per $\frac{1}{4}$ lawn mowed.

We will solve it by unitary method.

∵  $\frac{1}{2}$ gallon of gasoline is used to mow $\frac{1}{4}$ lawn.

∴ 1 gallon of gasoline is used to mow = $\frac{\frac{1}{4}}{\frac{1}{2}}$

                                                              = $\frac{1}{4}$ × $\frac{2}{1}$

                                                               = $\frac{2}{4}$

                                                              = $\frac{1}{2}$ lawn

you can mow $\frac{1}{2}$ lawn with one gallon of gasoline.
