Fractions of Dollars and Percents
Connect fractions, decimals, and percents to dollar amounts in Grade 6 math — convert between forms and calculate fractional parts of money in real-world shopping contexts.
Key Concepts
Property To find a fraction of an amount of money or a percentage, use the same two step process: divide the total amount by the denominator, then multiply the result by the numerator.
Examples How much is $\frac{3}{5}$ of 3.00 dollars? First, $3.00 \div 5 = 0.60$ dollars. Then, $3 \times 0.60 = 1.80$ dollars. How much is $\frac{2}{3}$ of 4.50 dollars? First, $4.50 \div 3 = 1.50$ dollars. Then, $2 \times 1.50 = 3.00$ dollars. What is $\frac{2}{5}$ of 100%? First, $100\% \div 5 = 20\%$. Then, $2 \times 20\% = 40\%$.
Explanation This awesome math trick works on money and percents, too! To find $\frac{3}{5}$ of 3.00 dollars, just divide the three dollars into 5 equal piles (60 cents each). Then grab 3 piles for a total of 1.80 dollars. The same goes for 100%: finding $\frac{2}{5}$ of it means dividing 100% into 5 parts and taking 2!
