A gardener uses a total of 61.5 gallons of gasoline in one month. Of the total amount of gasoline, [tex]\frac{3}{5}[/tex] was used in his lawn mowers. How many gallons of gasoline did the gardener use in his lawn mowers in one month?

A. 12.3
B. 24.6
C. 26.5
D. 36.9

Answer :

To find the number of gallons used in the lawn mowers, we start with the total amount of gasoline and the fraction used by the lawn mowers.

1. The total gasoline used in one month is
[tex]$$61.5 \text{ gallons}.$$[/tex]

2. The fraction used in lawn mowers is
[tex]$$\frac{3}{5}.$$[/tex]

3. Multiply the total gasoline by this fraction to determine the amount used in lawn mowers:
[tex]$$61.5 \times \frac{3}{5} = 61.5 \times 0.6 = 36.9.$$[/tex]

Thus, the gardener used
[tex]$$\boxed{36.9}$$[/tex]
gallons of gasoline in the lawn mowers.

The correct answer is D.
