Understanding Percent Problems

In this video, Mr. J explains how to solve percent problems using the percent equation. The video covers finding an unknown percent by using the equation 'percent times whole equals part.' Two examples are provided: one where the problem is '21 is what percent of 30' and another with different wording, 'what percent of 16 is 10.' The video demonstrates how to isolate the variable and convert the resulting decimal to a percent. The process involves identifying the whole and part, using inverse operations, and converting decimals to percentages.

What is the main focus of the video tutorial?

• Solving algebraic equations

In the percent equation, what does the term 'whole' refer to?

• The unknown value

• The total amount

• The part of the total

• The percentage value

How do you isolate the variable P in the equation P * 30 = 21?

• Add 30 to both sides

• Multiply both sides by 30

• Subtract 30 from both sides

• Divide both sides by 30
