To increase an amount by 15 percent, you should multiply it by 1.15. This is because 1 represents the original amount, and 0.15 represents the 15 percent increase. For example, if you have an amount of $100, multiplying it by 1.15 results in $115, which reflects the 15 percent increase.
To increase a number by a certain percent, multiply it by (1 + n/100). For example, to increase a number by 15 percent, multiply it by (1 + 15/100), or 1.15. To decrease a number by 15 percent, multiply it by (1 - 15/100), or 0.85.

To find 15 percent in pence, you need to calculate 15% of a specific amount in pounds and then convert it to pence. Since there are 100 pence in a pound, 15% of £1 is 0.15 pounds, which equals 15 pence. Therefore, 15 percent of £1 is 15 pence. If you have a different amount in pounds, simply multiply that amount by 0.15 and then convert to pence by multiplying the result by 100.
To calculate a 15 percent decrease, first determine the original amount. Then, multiply that amount by 0.15 to find the decrease in value. Subtract this decrease from the original amount to get the final value. For example, if the original amount is $100, the decrease would be $15, resulting in a final value of $85.

Multiply the percent times the dollar amount, then divide by 100. Add that amount to the dollar amount. For example: Add 15% to $1500. Multiply 15x1500 to get 22500. Then divide by 100 to get 225. Add the 225 to 1500 to get $1725.
