You should also take the opportunity to explain the importance and relevance of percentage calculations: pay rises, allowance rises, interest rates, discounts on sale items etc. Learning is always improved when the relevance of what is being learned is appreciated.

## What is a percentage?

Percent means “for every 100” or "out of 100." The (%) symbol as a quick way to write a fraction with a denominator of 100. As an example, instead of saying "it rained 14 days out of every 100," we say "it rained 14% of the time."

Percentages can be written as decimals by moving the decimal point two places to the left:

Decimals can be written as a percentages by moving the decimal point two places to the right:

**Math percentages**

A container holds 15 ounces of water if 9 ounces or spilled what percent of the water remains in the container?

There is a formula that you can use to get a percentage of something.

__PART OF WHOLE__

**WHOLE MULTIPLIED BY 100 = %**

**Let us try an example**

**1 \ 2 = .50 we multiply by 100 ( .50 x 100 ) = 50 %**

** In your case?**

**Your container becomes filled to capacity at 15 or 15 ounces.**

**Spilled was 9 ounces out of 15 ounces.**

__Part of Whole__

**Whole X 100 = %**

**9/15 = .60 ( we multiply by 100 ) = %**

**9/15 = 60 = %**

**9/15 = 60%**

**When the container is full it has 100%.**

** Then we must subtract ( the key word is spilled and not add or pour etc. ) from and not add to**

When her glass is at capacity it is 100%

100% - 60% ( **SPILLED **) = 40% ( **REMAINING CONTENT** )

**ANSWER:**

**REMAINING % IS 40%**

**Send me a message if you understand one possible solution to the problem**

** Now try this problem**

**Your parents gave you 100 cents. They instructed you to give your brother 40 cents. What percentage do you have left? What percentage did you give to your brother?**

Cont.

**The next day your brother decided not to keep his share but lend it to you for your lemonade stand. Your % and now his % equals how much % of the whole?**

** Glad I could help**
