Difficulty: EasyCalculating Percentages of Quantities

Read the scenario and calculate the correct numerical value to complete the statement.

Answer:A base supply warehouse holds 150150 replacement tires for tactical vehicles. If a maintenance unit requisitions 20%20\% of these tires for immediate use, the warehouse will issue 【30】 tires to the unit.

Answer

30
To find 20%20\% of 150150, you must convert the percentage to a decimal (0.200.20) or a simple fraction (15\frac{1}{5}). Then, multiply the total number of tires by this value: 150×0.20=30150 \times 0.20 = 30. Therefore, 3030 tires will be issued to the maintenance unit.

Step-by-Step Solution

1
Identify the total quantity and the percentage required.
Total tires = 150150, Percentage to issue = 20%20\%
These are the given values needed to find the partial amount.
2
Convert the percentage to a decimal or a fraction.
20%=0.2020\% = 0.20 (or 15\frac{1}{5})
Percentages must be converted into a workable numeric format before calculating a portion.
3
Multiply the total quantity by the decimal or fraction to find the final amount.
150×0.20=30150 \times 0.20 = 30
Multiplying the whole by the percentage rate gives the part of the whole.
