Part 1 - Describe how to find percents.

- 50% - take the number and divide it by 2
- 10% - take the number and divide it by 10
- 1% - take the number and divide it by 1
- 25% - take the number and divide it by 4
- You also need to define what a percent is - a percent is another term for "hundredths".

Part 2 - You need to show 3 images showing Representing Percents. You choose the 3 but you could

- 180%

- 12 3/4 %

- 0.7%

Part 3 - You need to explain how to convert from Decimals to Percents to Fractions. Choose 3 sets

- 26%

Decimals:

To convert percents to decimals, divide the number by a hundred (26 ÷ 100 = 0.26)

Fractions:

To convert percents to fractions, you have to find the decimal. Once you have found the decimal, find the place value of the last digit after the decimal. (0.2

Fractions:

To convert percents to fractions, you have to find the decimal. Once you have found the decimal, find the place value of the last digit after the decimal. (0.2

__6__= 26/100)- 7/10%

Decimals:

To convert fractions to decimals, divide the numerator and the denominator together. (7 ÷ 10 = 0.7)

Percents:

To convert fractions to decimals, multiply the decimal that you got by 100. (0.7 x 100 = 70)

- 0.024%

Fractions:

To convert decimals to fractions, find out the place value of the last digit of the decimal. (0.02

__4__= 24/1000)
Percents:

To convert decimals to percents, multiply the decimal to 100. (0.024 x 100 = 2.4)

Part 4 - Percent of a number is the next part of this exercise. Show how you could solve the following using mental math and a calculator.

- 20% of 60

Mental Math:

10% of 60 - 60 ÷ 10 = 6

6 x 2 =

Calculator:

20% of 60 - 60 ÷ 100 = 0.6

0.6 x 20 =

10% of 60 - 60 ÷ 10 = 6

6 x 2 =

**12**Calculator:

20% of 60 - 60 ÷ 100 = 0.6

0.6 x 20 =

**12**- 0.1% of 40

Mental Math:

40 ÷ 1000 = 0.04

Calculator:

1% of 40 - 40 ÷ 100 = 0.4

0.4 x 0.1 = 0.04

- 250% of 400

Mental Math:

400 x 2 = 800 - 400 ÷ 2 = 200

200 + 800 = 1000Calculator:

400 ÷ 100 = 4

4 x 250 = 1000

Part 5 - Combining Percents is the last part of this post. You need to explain Discount, Sale Price and Total Price with taxes. I also need you to explain what is a better deal 50% off or 25% off of an already reduced price of 25%. This can be done using the following questions,

**Discount**- Discount is a deduction from the usual cost of a selling object.

**Sale Price**- Sale Price is the lower price for the object(s) you are buying.

**Total Price With Taxes**- The total price with taxes is the final cost of the objects(s) you are buying. Depending where you live, you have to pay extra.

**QUESTION:**

What is the final sale price at each store? Which is a better buy?

Store A: 50% off one day only - $249

Store B: 25% off one day followed by 25% off the reduced price the second day - $249

Store A:

50% divide by 2

249 ÷ 2 =

**$124.50**

Store B:

25% divide by 4

249 ÷ 4 = 62.25

$249 - 62.25 =

**$186.75**

**Store A is better because you get to save more money. The difference is $62.25. Store A's discount was bigger making the price cheaper than Store B even if they discounted the price twice.**
