Final answer:
To calculate a percentage of a number, convert the percentage to a decimal by dividing by 100 and then multiply by the number. For example, 10% of 75 is 7.5, 1% is 0.75, 0.1% is 0.075, and 0.5% is 0.375.
Step-by-step explanation:
To find a percentage of a given number, you can multiply the number by the percentage expressed as a decimal. To convert a percentage to a decimal, simply divide by 100. For example, 10 percent becomes 0.10, 1 percent becomes 0.01, and so on. Let's calculate the requested percentages of 75.
10 percent of 75:
10% = ⅑₀₀
To find 10% of 75, you multiply 75 by 0.10:
10% of 75 = 75 × 0.10 = 7.5
1 percent of 75:
1% = ⅑₀₀₀
To find 1% of 75, you multiply 75 by 0.01:
1% of 75 = 75 × 0.01 = 0.75
0.1 percent of 75:
0.1% = 0.1 ÷ 100
To find 0.1% of 75, you multiply 75 by 0.001:
0.1% of 75 = 75 × 0.001 = 0.075
0.5 percent of 75:
0.5% = 0.5 ÷ 100
To find 0.5% of 75, multiply 75 by 0.005:
0.5% of 75 = 75 × 0.005 = 0.375
