Answer :
We are given that the gardener used a total of [tex]$61.5$[/tex] gallons of gasoline and that [tex]$\frac{3}{5}$[/tex] of this gasoline was used in his lawn mowers. To find the amount used in the lawn mowers, we multiply the total by the fraction:
[tex]$$
\text{Gasoline for lawn mowers} = \frac{3}{5} \times 61.5.
$$[/tex]
First, multiply [tex]$61.5$[/tex] by [tex]$3$[/tex]:
[tex]$$
61.5 \times 3 = 184.5.
$$[/tex]
Then, divide the result by [tex]$5$[/tex]:
[tex]$$
\frac{184.5}{5} = 36.9.
$$[/tex]
Thus, the gardener used [tex]$\boxed{36.9}$[/tex] gallons of gasoline in his lawn mowers in one month.
