Final Percent Post

This chapter, we learned about percent. Percent means out of 100. Percents can be converted into fractions and/or decimals.
75% - 75/100 or 0.75

Representing Percents
Percents can be represented on a hundred grid.

Example: 55%

Fractions, Decimals and Percents
Percents can be represented as a fraction or a decimal. Example: 50% ; 50/100 ; 0.5

Percent of a number
You can find percent of numbers by using mental math strategies. They are halving, doubling, a dividing by 10. Example: 50% of 1000 is 500

Combining Percents
Combine percents by adding to solve the problems. Example: 5% + 7% = 12%
