Percentage Practice Problems - Calculate Parts of a Whole

To find 15% of 100, you can convert the percentage to a decimal by dividing by 100:

$15\% = \frac{15}{100} = 0.15$

Next, multiply this decimal by 100:

$0.15 \times 100 = 15$

Thus, 15% of 100 is 15.

To find 8% of 100, first convert the percentage to a decimal by dividing by 100:

$8\% = \frac{8}{100} = 0.08$

Then, multiply this decimal by 100:

$0.08 \times 100 = 8$

Hence, 8% of 100 is 8.

To find 45% of 100, you can multiply the percentage as a decimal by the whole number. First, convert 45% into a decimal. This is done by dividing by 100: $45\% = \frac{45}{100} = 0.45$.

Then, multiply this decimal by 100: $0.45 \times 100 = 45$.

Therefore, 45% of 100 is $45$.

To find 35% of 100, first convert the percentage into a decimal by dividing by 100: $35\% = \frac{35}{100} = 0.35$.

Then, multiply this decimal by 100: $0.35 \times 100 = 35$.

Therefore, 35% of 100 is $35$.

In order to determine what percentage 25 is out of 100, we use the following formula:

$\text{Percentage} = \frac{\text{Part}}{\text{Whole}} \times 100\%$

.

We begin by substituting in the known values:

$\text{Percentage} = \frac{25}{100} \times 100\% = 25\%$

.

Thus, 25 out of 100 is $25\%$.
