ex. 75% means 75 out of 100 or 75/100 or 0.65.

**4.1 Representing Percents**

-This section talks about how to represent percents in different ways like representing them on a hundred grid.

ex. to represent 50% on a hundred grid, you would shade in 50 units.

**4.2 Fractions, Decimals, and Percents**

- Fractions, decimals, and percents can be used to represent numbers in various situations.

-Percents can be written as fractions and decimals.

ex. 15% = 15/100

= 0.15

**4.3 Percent of a Number**

-You can use mental math strategies such as halving, doubling, and dividing be ten to find the percents of some numbers.

-To calculate the percent of a number, write the percent as a decimal and then multiply the number.

ex. 25% of 50 = 0.25 x 50

= 12.5

**4.4 Combining Percents**

- Percents can be combined by adding to solve problems.

ex. 5% + 7% = 12%

- To calculate the increase of 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 of decreases.

Good job, Kim! I liked how you only used black but did the titles in bold because in my opinon I like to keep it plain instead of all flashy with colors. Keep it up!
