Finding the formula for percentage, rate and base using TECHAN'S Triangle

The percent, base, and rate are connected with one another in terms of computation. To find the percentage, multiply the base by the rate. Remember that the rate must be changed from a percent to a decimal before multiplying can be done. Rate times base equals percentage.

PERCENTAGE (P=BxR) – The result obtained when a number is multiplied by a percent.

BASE (B=P/R) – The whole in a problem. The amount you are taking a percent of.

RATE (R=P/B) – The ratio of amount to the base. It is written as a percent.
