**percent**means out of 100 and it also another name for hundreths

**Ex**. 75% means 75/100, 75 out of 100, or 0.75

**4.1 Representing Percents**

Representing percents means showing a percent as a picture in a hundred grid

**Ex**. 25% on a hundred grid, 25 squares of the grid would be shaded so its 25%

**4.2 Fractions, Decimals, and Percents.**

- Fractions, Decimals, and Percents can be used to represent numbers in various situations

- Percents can be written as a fraction and as decimal

**Ex**. 1/2% = 50%, 0.5% = 0.5/1000 = 0.005, 150% = 150/100 = 1.5, 42 3/4 = 42.75% = 42.75/100 = 0.4275

**4.3 Percent of a number**

- You can use mental math strategies such as halving, doubling, and dividing by ten to find the percent of same numbers

- To calculate the percent of a number, write the percent as a decimal then multiply by the numbers

**Ex**. 12 1/2% of 50, 0.125 x 50 = 6.25 (12 1/2% = 12.5% = 0.125)

**4.4 Combining Percents**

**-**Percent can be combined by adding to solve problems ; 5% + 7% = 12%

To calculate the increase in a number you can add the combined percent amount to the original number.

**Ex**. 12% of 100 = 0.12 x 100 = 12, 100 + 12 = 112

- You can multiply the original number by a single percent greater than 100

**Ex**. 112% of 100 = 1.12 x 100 = 112

- Percents of percents can be used to determine amounts that result from consecutive percent increases or decrease
