6. Mr Clark had a gas can with \( 41 / 2 \) gallons of gasoline in it. He used \( 1 / 4 \) of the a mount in the can to mow his lawn. How many gallons did Mr. Clark use to mow his lawn?

Mr. Clark started with \( 41 / 2 \) gallons, which is the same as \( 4.5 \) gallons. To find out how much he used, we need to calculate \( 1 / 4 \) of \( 4.5 \) gallons. Multiplying \( 4.5 \) by \( 1/4 \) gives us \( 4.5 \times 0.25 = 1.125 \) gallons. Therefore, Mr. Clark used \( 1.125 \) gallons of gasoline to mow his lawn. It's interesting to note how quickly such computations arise in real life! If you ever find yourself in a similar situation and want to use a bit less gas, consider strategies like mowing when the grass is dry, which can cut down on your fuel usage by requiring less power from the mower. Solutions can often be found with a little creativity and planning!
