What is the Percent Equation?

What is a percent equation?

Summary

  1. '%' means percent
  2. 'a' represents the number we're looking for
  3. In math, 'is' means 'equals'
  4. In math, 'of' means 'times'
  5. We need to convert the percent to a decimal to use it in a percent equation
  6. You can turn a percent into a decimal by dividing it by 100, or moving the decimal two places to the left
  7. All percent equations will look like the equation 'part=percent•whole'
  8. In our example, 'a' is the part, 40% is the percent, and 30 is the whole

Notes

    1. 'a' represents the number we're looking for
    2. In math, 'is' means 'equals'
    3. We need to write 40% as a decimal in order to use it in the equation
    4. 40% is the same as 0.4
    5. In math, 'of' means 'times'
    6. So when we translate this phrase we get 'a=(0.4)(30)'
    1. All percent equations will look like the equation 'part=percent•whole'
    2. You'll have to change any percents you have into decimals before you can multiply them
    1. In the first example, let's find the percent
    2. 'p' stands for 'percent'
    3. Remember, the percent in the percent equation must be in decimal form
    4. In the second example, let's find the part
    5. 'a' stands for the part of the whole
    6. In the last example, let's find the whole
    7. 'b' stands for the whole
