An aviation unit's weekly fuel allowance is $4,000$ gallons. If they have used $60\%$ of their allowance during training exercises, how many gallons of fuel have they used?

A
$240$
B
$3,940$
$2,400$ Answer
D
$6,400$

Answer

2,400

To find how much fuel was used, we calculate

60\%

of the total

4,000

gallons. Converting

60\%

to a decimal gives us

0.60

. Multiplying

4,000

0.60

results in

2,400

gallons.

Step-by-Step Solution

Convert the percentage to a decimal or fraction.

60\% = 0.60

Percentages must be converted into a workable mathematical format like a decimal before multiplying.

Multiply the total weekly allowance by the decimal to find the amount of fuel used.

4,000 \times 0.60 = 2,400

gallons

Multiplying the total quantity by the percentage (as a decimal) yields the portion that represents that percentage.

Key Concept

To calculate a percentage of a quantity, convert the percentage to a decimal (or fraction) and multiply it by the total quantity.
