Representing percents
What You'll Learn
Calculate percents of whole numbers and decimals using loading strip models
Determine percentages by dividing numbers in half repeatedly (50%, 25%, 12.5%)
Find 10% by dividing by 10 and understand percent as 'per hundred'
Combine percentages by adding their decimal values (75% = 50% + 25%)
Convert between percents, fractions, and division to solve problems
